[0007] Wind farm maintenance is an important task in the operation and maintenance of wind farms. Compared with conventional power sources such as thermal power and hydropower, wind farms have the characteristics of wide geographical distribution, large number of units, complex and changeable natural environment, and large seasonal differences in wind power output. , so that the wind farm cannot guarantee the efficiency of power generation during maintenance

Abstract

The invention discloses a method for optimizing a maintenance plan of an electric power system comprising large-scale wind power, objective functions are built, and constraints are carried out on the objective functions to obtain optimum optimized results. The constraint conditions are respectively a constraint according to the maintenance natural environment, a constraint according to maintenance time of a wind power farm, a constraint according to maintenance field of the wind power farm, a constraint according to system reliability of the wind power farm and a constraint according to maintenance continuity of a generating set. Under the constraint conditions, the objective functions are adopted for carrying out modeling on the electric power system through a heuristic algorithm. Due to the fact that the modeling is carried out on the electric power system comprising the large-scale wind power, under the certain constraint conditions, through the modeling, reasonable maintenance time optimizing is carried out on wind power generators in the electric power system, so that the purpose that while maximum efficiency of wind power generation is ensured, wind power equipment is maintained reasonably is achieved.

Description

technical field [0001] The invention relates to the field of wind farm maintenance, in particular to a maintenance plan optimization method for a power system containing large-scale wind power. Background technique [0002] At present, due to the reliable power generation capacity and good regulation ability of conventional generating units such as thermal power and hydropower, the impact on the power grid during their maintenance is mainly reflected in the reliability of power supply. When arranging the maintenance of conventional generating units, it is generally considered to ensure the power supply reliability of the power grid , the corresponding methods include equal standby method, equal risk degree method and so on. Compared with conventional generators such as thermal power and hydropower, wind turbines have their particularity, so the impact of wind farm maintenance on the power grid is also different from that of conventional generators. [0003] Since wind farms...
