Amistad_Falcon PP One Line Diagrams.pdf

This document consists of two technical schematic diagrams related to the Falcon Dam and Power Plant project on the Rio Grande between the United States and Mexico.

The first page is a Main One-Line Diagram Control System schematic for the International Boundary and Water Commission (IBWC) facility. It depicts the electrical control system architecture with various components including power circuit breakers, disconnected switches, current transformers, potential transformers, relaying equipment, synchronizing switches, and associated instrumentation. The legend identifies numerous electrical components and their abbreviations. Notes indicate that the Power Schedule was completed on day 271, and the schematic references the requirement for a slave set (not 1) to be included. The diagram shows the HWMC-AMISTAD PP Equipment Responsibilities area highlighted in red, delineating the scope of equipment for which the Power Plant operator is responsible.

The second page is a Single Line Metering and Relaying Diagram (OA-4-230) for the Falcon Dam and Power Plant Switching Diagram for the U.S. section. This schematic illustrates the power transmission and distribution network showing connections to the Mexican Switchyard, Edinburg, and Laredo, with transformer stations (KD1A through KD4A), voltage regulators, and local load distribution. The Falcon PP Equipment Responsibilities area is again highlighted in red, clearly demarcating the equipment scope boundaries. Both documents are reference drawings supporting the international dam facility's operational infrastructure.
