3.1.1.1 NODE DESCRIPTION

The Node 3 is a pressurized element providing locations for Environmental Control and Life Support System racks, crew equipment, and berthing locations for attached elements. The Node contains a limited amount of powered hardware for its own operations and plumbing and cable runs to the attached elements.

3.1.1.2 CUPOLA DESCRIPTION

The Cupola is a controlling workstation that provides full hemisphere viewing for monitoring of exterior station activities.

3.1.1.3 INTERFACE PLANE DESCRIPTION

The structural/mechanical interface plane is between the Active CBM (ACBM) and Passive CBM (PCBM) as defined in SSP 41148 and shown in Figure 3.1.1.311. The utility interface plane is between the bulkhead of the Node and ACBM as shown in Figure 3.1.1.3−1.

Notes:

Rationale for the Proposed Source Impedance Curves

(1) The Cupola receives power from the Node 1 or Node 3. Figures 3.2.1.3.1.3−1.1 and

3.2.1.3.1.3−1.2 show the Node 1 to Cupola and the Node 3 to Cupola power distribution circuits respectively. The ATU is powered through a 20 awg cable and the UOPs are powered through 12 awg cables.

(2) The distance from the source to the Node 1 to Cupola Interface falls in the range of 100−200 feet. The distance from the source to the Node 3 to Cupola Interface falls in the range of 50−100 feet. Node 1 is the powered from a single DC−to−DC Converter Unit (DDCU) while Node 3 is powered from parallel DDCUs. The Node 1 and Node 3 configurations match the configurations used to generate the location−specific source impedance curves of SSP 30482, Vol 1, Rev C.

(3) Even though the source impedance curves in SSP 30482, Vol. 1, Rev. C assume a single DDCU source, at Interfaces that are in excess of 50 feet from the source, the SSP 30482, Vol. 1, Rev. C location−specific curves are applicable for the Node 3 circuits since the cable impedances dominate the source impedances making the contributions of parallel DDCUs insignificant.

(4) During the Node 1/Cupola subsystem simulations, the MDM and the Ceta Luminaire were powered in RPDA N1−RS2. Being constant power loads, the MDM and the Ceta Luminaire are important loads to consider in system stability analyses. Heater loads were not connected in the system to represent a worse case scenario for stability.

(5) The source impedance definitions at the Node to Cupola Interfaces that are derived from the curves in SSP 30482, Vol. 1, Rev. C, include the effects of side loads for known ISS architectures. We believe that these curves should be adequate to include the effects of side loads in Node 3 but we are unable to show this in the analysis of the Node 3 /Cupola subsystem because of lack of detailed information on Node 3.

(6) Figures 3.2.1.3.1.3−1.3 and 3.2.1.3.1.3−1.4 display the model−produced source impedances at the Node 1 to Cupola Interface (I/F) to the ATU and at the ATU Interface C. The source impedance magnitude and phase measured at the Cupola I/F to the ATU satisfy the boundaries outlined in this PIRN. The source impedance magnitude and phase measured at the ATU Interface C meet the SSP 30482, Vol. 1, Rev. C standard I/F C requirements for 5 Amp. power feeds.

(7) Figures 3.2.1.3.1.3−1.5 and 3.2.1.3.1.3−1.6 display the model−produced impedances at the Node 1 to Cupola I/F to the UOP and at the UOP output Interface C. The source impedance magnitude and phase measured at the Cupola I/F to the UOP satisfy the boundaries outlined in this PIRN. The source impedance magnitude and phase at the UOP output Interface meet the SSP 30482, Vol. 1, Rev. C standard I/F C requirements for 12 Amp. power feeds.

(8) Figures 3.2.1.3.1.3−1.7 and 3.2.1.3.1.3−1.8 display the model−produced source impedances at the Node 3 to Cupola I/F to the ATU and at the ATU Interface C. The source impedance magnitude and phase measured at the Cupola I/F to the ATU satisfy the boundaries outlined in this PIRN. The source impedance magnitude and phase measured at the ATU Interface C meet the SSP 30482, Vol. 1, Rev. C standard I/F C requirements for 5 Amp. power feeds.

(9) Figures 3.2.1.3.1.3−1.9 and 3.2.1.3.1.3−1.10 display the model−produced impedances at the Node 3 to Cupola I/F to the UOP and at the UOP output Interface C. The source impedance magnitude and phase measured at the Cupola I/F to the UOP satisfy the boundaries outlined in this PIRN. The source impedance magnitude and phase at the UOP output Interface meet the SSP 30482, Vol. 1, Rev. C standard I/F C requirements for 12 Amp. power feeds.

Results

Saber simulations are performed to measure source impedances at the Cupola Interfaces.

The Saber models incorporate DDCU, Remote Power Controller Module (RPCM) and cable models. The results from the simulations are compared against appropriate source imped-ance definitions/requirements.

The Cable Model Parameters table below shows the resistance and inductance values for 20 awg and 12 awg cables respectively. For cable inductance values that are lower than those shown, the analysis results are expected to show improved compliance with source imped-ance definitions/requirements.
