An AGC control device and an integrated power generation system

Abstract

The embodiment of the invention provides an AGC control device which comprises an AGC instruction formation circuit of new energy access and a plant level load instruction distribution circuit. The AGC instruction formation circuit of new energy access is used for compensating an AGC instruction of a gas turbine power plant sent by a dispatching center according to a deviation value of a regional power generated by new energy power generation. The plant level load instruction distribution circuit is used for distributing and adjusting a load instruction of a gas turbine according to the actual power generation power of the gas turbine and the AGC instruction compensated by the AGC instruction formation circuit of new energy access. According to the system, a regional grid power generation power deviation value caused by renewable new energy intermittent power generation can be compensated through a gas turbine power generation set, thus the whole power generation system can output smooth power generation power, an adverse effects of the renewable new energy intermittent power generation on a power grid is eliminated, the fluctuation of new energy intermittent power generation power in a regional grid is stabilized, and the power generation power complementary of a gas turbine power plant and a new energy power plant is realized.

Description

technical field [0001] The invention relates to the field of control devices, in particular to an AGC control device and an integrated power generation system. Background technique [0002] At present, most of the energy for power generation comes from fossil fuels. The burning of fossil fuels has brought serious pollution to the environment on which human beings depend. Wind energy, solar energy and other renewable energy sources are non-polluting and have huge reserves. General attention. In recent years, renewable new energy power generation technologies represented by wind energy, solar energy, and biomass energy have developed rapidly. However, new energy power generation has the characteristics of randomness and uncontrollability, and its power generation is intermittent. The generated power will generate disturbances, if not absorbed in time, it will cause fluctuations in the generated power of the regional power grid. How to use conventional power plants and new en...
