Abstract

The invention belongs to the technical field of hydroelectric generation equipment, and particularly relates to a no-load adjustment parameter optimization method for an impact type hydro-generator speed regulator. In order to optimize the parameters of the impulse turbine governor and improve the stability of the impulse turbine generator in the operation process, the invention discloses a method, which comprises the following steps: determining ITAE indexes as optimization evaluation targets by introducing an impulse turbine generator speed regulation system related mathematical model; obtaining an optimal individual of the current population according to an improved algorithm, updating the next generation of individuals, and guiding the algorithm to carry out global search. In the population updating process, the individuals and the population are continuously updated by adopting a differential evolution thought, so that the historical information of the dominant individuals is fully utilized, and the global search of the algorithm has a certain width; in the selection stage of the algorithm, a probability mechanism is adopted to update individuals, and in the mutation operationstage, the F factor is optimized, so that the search field of the algorithm is wider; therefore, the solution quality is obviously improved.

Description

technical field [0001] The present application relates to the technical field of hydroelectric power generation equipment, in particular to a method for optimizing no-load adjustment parameters of a speed governor of an impact type hydroelectric generator. Background technique [0002] Water energy is the potential energy and kinetic energy stored in rivers and ocean water bodies. It is a clean primary energy source and an inexhaustible renewable energy source. Hydropower can convert water energy into electrical energy, which can then be used by people. [0003] The basic principle of hydroelectric power generation is to use the water level drop to cooperate with the hydroelectric generator to generate electricity, that is, to use the potential energy of the water to convert the mechanical energy of the waterwheel, and then use the mechanical energy to drive the generator to obtain electricity. Scientists take advantage of the natural conditions of the water level drop to e...
