GENERAL SYSTEM NOTES

1. The emergency paralleling system will be furnished in an Integrated Switchgear line up per Medium Voltage

UL, ASCO File No. E142645 manufactured in accordance with applicable ANSI, NEMA and IEEE Standards and utilizes insulated copper bus bars. Switchgear design will be freestanding, sheet metal enclosed, and floor supported, with front and rear access. All doors will be formed type, minimum of 11 gauge steel and will have sufficient hinges to support the door and components for an absolute minimum deflection when opening or closing. Doors swing open more than 90 degrees for safety and easy of accessibility and will have lockable handles. All panel covers are formed type, and secured with screws as necessary. Refer to project specific drawings for shipping splits.

2. All locks will have identical keying and can be operated from a single key. Openings will be included for air circulation. Finish will be ANSI 61, switchboard light gray, baked powder, over a fully cleaned, degreased, rust inhibiting surface.

3. Internal control wiring will be rated at 600 volts and made with SIS type for Medium Voltage. All wires will be numbered every eight inches as well as at both ends.

4. All electric and electronic controls associated with engine generator sets such as voltage regulator, governor, etc. shall be provided and mounted at the engine generator sets by others.

5. Load banks are required to set up load sharing between generators. They may also be required for final system sequence testing if site load is not available. Load banks must be both reactive and resistive. ASCO will not be responsible for providing load banks, cables for connecting load banks or items associated with load banks as required for load bank testing. This shall be responsibility of others.

6. Cable termination boots/taping and stress cones are to be provided by the installing contractor and are not included in ASCO’s scope of work.

7. Field service support hours are based on a normal working week.

8. All generators should have the same pitch for stable operation and to minimize circulating currents between running machines, false tripping of generator circuit breakers, temperature increase in the neural bus and neutral conductors caused by harmonics, etc. It is responsibility of others to determine if the pitch of all engines is same or different and to provide any resolution to the issues caused by paralleling different pitch engine generators. Synchronizing controls cannot compensate for different pitch engine generator sets.

9. ATS Power Managers in ASCO supplied equipment and third party meters installed in switchgear supplied by others will interface with ASCO PowerQuest. The following will be trended Ia, Ib, Ic Vavg, kW, KVA, KVAR, PF, and Frequency, utilizing Modbus. Power Quality and Wave Form capture capability are not included.

10. ASCO’s scope of work does not include a short circuit and coordination study or subsequent relay calibration and settings.

11. ASCO scope of supply does not include onsite assembly/set up of ASCO supplied station battery system.

12. If compliance with NEC article 700.10 is required, information must be provided as to which breakers are designated as emergency, legally required or optional. Any changes will require ASCO to amend this proposal.

13. The customer will be responsible for providing 120VAC input for UPS in ASCO switchgear.

- Normally Closed o PS-3, PS-5 (Essential loads 1EM1 & 6EM1)

Please reference Overall customer one line (Drawing E-607)

II. OPERATING MODE (S)

A. Emergency Mode

Whenever the individual engine generator control switches are placed in their automatic position, the engine generator system is on standby in readiness for automatic starting and synchronization in the event of a power failure signal.

In the event of a power failure, all generator(s) automatically start and come up to speed. The first generator set to achieve 90% of nominal voltage and frequency shall be connected to the bus.

Electronic interlocks permit the connection of only one engine generator to the dead generator bus in the event of simultaneous generator relay operation. Normally closed feeders (PS-3 & PS-5) will be energized as soon as the first generator comes on to the bus. Immediately thereafter, normally open feeder breakers (PS-4, PS-6, PS-1, and PS-2) will step add in that order to the emergency bus in one second intervals. Upon sensing the availability of emergency power, the priority-1 load block will be allowed to transfer their loads to the emergency bus, through a “permissive signal” to the automatic transfer switches (if equipped), subject to their individual Step Add timers as detailed in section B. Block Load Control. (Note: If priority 1 loads are not calling for an engine start because they have not lost normal power, a priority-pass along feature will be activated. Generally, if no loads in any priority block are calling for an engine start, all loads in lower priority blocks will be shifted up to a higher priority for block load add/shed purposes.) The synchronizer will automatically adjust the frequency of the on-coming generator to synchronize with the bus. When synchronism is achieved, the on-coming generator is paralleled to the bus. When the second generator’s circuit breaker is closed the priority-2 load block will be allowed to transfer their loads to the emergency bus. As each generator parallels to the bus, another block of load is allowed to add, until all generators and all loads are online.

Note - Load Bus J1 & Load Bus J2 are manually operated switchboards and require manual operation due to kirk key application.

Switchgear Feeder breakers feeding Load Bus J1 & Load Bus J2 (Switchgear Feeder Breakers:

PS-1 & PS-2) will close on emergency bus as the generators are coming on to the bus;

however, it will not energize the load until manually closed by operator on the side of the Kirk key operated equipment.

Upon sensing that normal utility power has been restored to acceptable limits, a sequence shall begin to transfer the load back to the utility source. The re-transfer shall be initiated after the retransfer to utility time delay has expired (adjustable at each ATS from 0 minute to 30 minutes) allowing an open transition transfer return to utility.

All feeder breakers on SWGR-GEN (12654P) feeding the loads will open and return to Utility except feeder breakers PS-1 & PS-2 feeding Load Bus J1 & Load Bus J2 respectively.

Therefore, the paralleling switchgear and ATSs associated (if any) with Load Bus J1 & Load Bus J2 in Building #5 already in Emergency will remain on Emergency and will not fully return to respective Utility until Load Bus J1 & Load Bus J2 are manually opened due to existing kirk key application on its respective utility breakers. (Load Bus J1 and Load Bus J2 will send signal to SWGR-GEN (12654P) via dry contacts (Aux contacts to be provided by customer) once kirk key is manually engaged and then ATSs will retransfer upon sensing Utility source and begin generator cooldown for the generators designated to continue running via Generator Load Demand)

After all the transfer switches have re-transferred their loads to the normal source, the generator circuit breakers are simultaneously opened and the engine generators run for an adjustable no-load cool-down period of zero to thirty minutes; factory set at 5-minutes. The controls are released and the generators placed in readiness for the next power failure.

B. Block Load Control

Each load has an adjustable priority setting, estimated KW value and step time delay associated with

it. As each block of load is allowed to transfer to emergency power, the individual loads will begin their step time delay. As the time delay for each load completes, the load will receive a permissive signal to transfer to emergency power. If no delay is desired, the individual step times can be set to zero seconds, and the loads will transfer immediately when the load block is permitted to transfer to emergency.

Note: Any automatic transfer switch without the 30B accessory (Load Shed) will automatically transfer to emergency on its own regardless of the permissive signal. Typically, critical priority 1 loads will not have a 30B accessory.

If a generator fails while operating in the automatic mode, it is disconnected from the bus and shutdown. Audible and visual alarms will be activated to indicate the condition. System loads will not shed unless a bus overload or a bus under frequency occurs. This feature is referred to as “Load- Latch”.

A push-button permits override of the load-shed circuits for supervised operation (one for each priority except priority 1). Loads that have been block shed can be manually re-added using the priority-# Load Shed Bypass/Reset push-button located on the Master control section. By pressing the Load Shed Bypass/Reset push-button, the system will transfer the selected load block to the emergency bus. By pressing the Load Shed Bypass/Reset push-button a second time, the ENTIRE selected load block will shed. Indicating lights will annunciate the status of each Priority load block, indicating if it is shed or manually bypassed. If the operator inadvertently bypasses the load shed and overloads the Generator(s) resulting in a bus under-frequency, all manually bypassed loads will be automatically shed along with blocks of load such that the remaining load blocks shall be one less than the number of generators remaining on the bus. The “Bus Under Frequency” annunciator light will indicate this condition.

If the online load exceeds 105% of rated generator capacity, unsupported loads (loads in priority blocks greater than the number of generators online) will be step shed in reverse priority at one second intervals. No loads in priority blocks equal to or less than the number of generators online will be shed. (Ex. If you have three generators online, load blocks 1. 2, and 3 will stay online, priority 4 and above will be shed). The Bus Overload light will light to indicate that the bus is overloaded automatically reset as the overload is corrected. When the online load no longer exceeds 105% of the generator capacity, step shedding will cease, and the system will continue to power the loads that are left online. Indicating lights will annunciate the status of each Priority load block, indicating if any loads in that block are shed or if the load block is manually bypassed. If the operator bypasses the load shed to bring those shed loads back online, and the online load exceeds 105% of capacity again, the system will again step shed loads in reverse priority until the load no longer exceeds 105% of capacity.

This is done in an attempt to prevent an under frequency situation, thereby preventing the entire load block from being shed.

III. Features

A. Load Bus Optimization

Each load should be programmed with a load priority value (field adjustable, accessible via the OIT on the master section door). A load’s priority value is a 3-digit number. The most significant digit refers to the load’s block priority value (i.e. 201 => priority 2 load block, whereas 118 => priority 1 load block).

The two lower significant digits refer to the load’s sub-priority value, or load step priority (i.e. 201 => priority 2 block, step 1; and 118 => priority 1 block, step 18). Valid priority values are 1 – 10 while valid sub-priority values are 1 - 99. Therefore, valid three digit priority values are 101 - 1099. Note: priority 1 loads (101 - 199) have insignificant sub-priority values since priority 1 loads are never optimized, also 3 digit priority values of 200, 300 and 400, etc. are not valid priority numbers. However, because of the dynamic nature of the adjustable load priorities, all loads, even priority 1 need to have sub-priority step values.

Should a Priority Block fail to be added to the bus while operating in the Emergency Mode, loads may be added manually by the operator as described above in section B. Block Load Control or automatically through "Load Bus Optimization". Load Bus Optimization is provided to re-add shed loads one at a time based on predetermined kW loading values up 95% (adjustable via OIT) of the capacity of the on-line power. This percentage value is referred to as the Bus Optimization KW de-rating value.

With the Bus Optimization switch in the "on" position during emergency mode and with loads shed (loads requiring power but are not connected to the emergency bus), after a stabilization time delay (Bus Opt stable delay) the optimization feature is activated and a Bus Optimize Active light illuminates.

The Bus Optimize Active light flashes through the duration of the stabilization time delay (default 30 seconds, adjustable via OIT). At this time, the Bus Optimization loading control will determine if there is enough room to add the next load by checking the pre-set Load Value (field adjustable, accessible via the OIT) assigned to the first sub-priority within…
