System, method and equipment for dispatching active power of wind power plant

Abstract

The system comprises a power scheduling module, a wind generating set, a telecontrol device, a frequency measurement device, a station energy management platform, an environment measurement device, a centralized monitoring platform and a field group control platform. The telecontrol equipment, the frequency measurement device, the field station energy management platform, the environment measurement device, the centralized monitoring platform and the field group control platform are all connected to the power scheduling module; the plurality of wind generating sets are connected to the power dispatching module; according to the method, active power scheduling conflicts caused by different requirements of a power grid side, a station side and a fan side in a traditional mode are overcome by adopting a mode of setting the active power scheduling instruction priorities, so that the active power scheduling priorities of different requirements are fully considered; and the active power control requirement of the wind power plant with the highest priority is timely responded to the maximum extent.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a system, method and equipment for active power dispatching of wind farms. Background technique [0002] As wind power more and more participates in the production of electric energy, the demand for the active power output that each generator set or even each wind farm can emit is also more and more diverse. It can be roughly divided into several categories. The first category is to participate in grid active power regulation, with AGC automatic generation control, which sends active power commands to wind farms through grid dispatching and telecontrol equipment; primary frequency modulation and inertia response, which pass frequency measurement The device calculates the frequency change amount and frequency change rate and the corresponding active power frequency modulation command; the second type is the wind farm level platform, which has a station energy management platfo...

AI Technical Summary

Problems solved by technology

However, the scheduling priority instruction at the station level and the active power scheduling priority of a single wind turbine have not been considered uniformly. When conflicts occur, the active power adjustment effect cannot meet the design requirements.

At the same time, because many active power adjustment priorities have not been considered as a whole, there will be certain difficulties in making actual modifications in the future
