PURPOSE:To enable a favorable balance to be secured between supply and demand of power, by making increasing and decreasing control according to load fluctuation by means of a general drooping characteristics arithmetic circuit and a ratio regulator mounted to a load distribution control apparatus of a generating plant consisting of plural number of turbine generators. CONSTITUTION:In a load distribution control apparatus for controlling plural number of turbine generators 1-3, an adder 42 is connected to a general load setter 41, and also each ratio regulator 15 receiving the ratio of a load distributed to each of generators 1-3 after branching from the adder 42 is also connected thereto. Each ratio controller 15 is connected to a revolution setter 16 mounted to the governor of each of generators 1-3 and at the same time, outputs taken out from generator main circuits 51-53 are fed back to the respective ratio controllers 15 through LPF 17 of output. Moreover, by providing a circuit for detecting frequencies accompanying the load fluctuation of power system from a transmission line 54, the set value of the total load is automatically corrected by the general droop characteristic arithmetic circuit 43 based on the deviation amount thereof so that it may be output to the adder 42. |
