Abstract

The invention discloses a power distribution method based on photovoltaic and hydropower combined power generation, and belongs the technical field of power system power generation. The power distribution method comprises the following steps: establishing an electric power detection system; designing a processing system; and the processing system receives the data from the electric power detectionsystem to drive a power generation control device to adjust the total output power. Voltage sensors and current sensors are utilized to detect the power of solar power generation and hydropower generation, then the data calculation unit is utilized to calculate and compare the MCU with the comparison unit and then the water flow gate on the hydraulic power generation system can be controlled, theflow rate and flow rate can be controlled, the power generation quantity can be changed and the output end on / off of solar power generation can be controlled and the power generation quantity can bechanged and the total power can be kept constant. The method has high automation degree and time and labor saving and has market promotion value.

Description

technical field [0001] The invention relates to the technical field of power system power generation, in particular to a power distribution method based on photovoltaic and hydropower combined power generation. Background technique [0002] With the concentrated construction of large-scale solar farms in my country, the installed capacity of solar farms continues to increase, and the proportion of solar power generation in the power grid is increasing. Due to the regional and intermittent characteristics of solar power generation, this brings many problems to the safe dispatch of the power grid. And the same problem exists in hydroelectric power generation, and then the actual annual utilization hours of solar generators and hydroelectric generators are few. When the output of solar power generation is low, the hydropower plant can run at full power to improve the economic benefits of the hydropower station. When the amount of solar power generation is large, in order to en...
