The invention discloses a dual-PID water turbine generator set regulating system under a power control mode, which comprises a PID regulating module and a water turbine power generation module, and ischaracterized in that the PID regulating unit includes a monitoring unit, a frequency deviation calculating unit, a power deviation calculating unit, a first PID functional unit used for executing primary frequency modulation regulation, a second PID functional unit used for executing AGC regulation, a first switching control unit, a second switching control unit and an output adder; and the water turbine power generation unit includes a water turbine generator set and an execution mechanism. The dual-PID water turbine generator set regulating system under the power control mode disclosed bythe invention can effectively solve a problem that the it is difficult for a water turbine generator set to coordinate two regulating modes under the power control mode in the prior art.
Description
technical field [0001] The invention relates to the field of electric power system control, in particular to a dual-PID water turbine generator set regulation system under power control mode. Background technique [0002] The regulation system of the turbine governor is one of the important auxiliary control equipment of the hydro-generator set, and the hydro-generator set can participate in the frequency regulation of the power system through the governor system. In the grid-connected mode, the turbine regulation system generally has two modes to choose from: power control mode and opening control mode. Compared with the opening control mode, the power control mode has the characteristics of fast adjustment speed, smooth adjustment and accurate adjustment. The short-term frequency regulation of power system can be divided into two regulation methods: primary frequency regulation and automatic generation control (AGC) regulation. [0003] In the existing hydro-generator se...
