POWER SYSTEM LOAD FREQUENCY CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To obtain a load frequency control system effective for controllability and economy of power system. SOLUTION: For a generator performing raising (lowering) command by an economic load distribution control(EDC) to means 24 distributing area request power(AR) for each generator and to means 221 computing target command value to each generator based on area request power(AR), the area request power(AR) is not distributed when the area request power(AR) is a positive value (negative value) in a power system.
