Automatic Generation Control Response Tests Performed for Western Area PowerAdministration's Upper Colorado/Lower Missouri Control Area

摘要

In October 1993, Reclamation's Electric Power Branch in the Research andLaboratory Services Division received a request from Western (Western Area Power Administration) to test the AGC (automatic generation control) response within the WACM (Western Area Upper Colorado/Lower Missouri) combined control area. Attempts at control of the combined area revealed differences in generation response rates between Glen Canyon and Yellowtail powerplants. Western requested that the Electric Power Branch review the generation response capability of the powerplants in the combined control area. This report documents the results from the testing and presents conclusions based on the test results. Observations made while executing tests at the control centers are also included. A simple model of the system was constructed. Conclusions are made based on laboratory model tests. Recommendations are made to improve AGC control of the combined control area. A short-term modification is suggested to make the AGC more functional; however, a long-term direction must be pursued to provide AGC regulation from multiple powerplants in WACM while maintaining Reclamation release schedules and constraints.
