The present invention discloses a testing method for dynamic model parameters of a wind power plant, wherein under testing conditions including stable running of wind turbine generators and reactive-load compensation equipment, stable wind speed between a cut-in wind speed and a rated wind speed, and the wind power plant output smaller than a rated output, finishes a wind speed transient disturbance test, a wind power plant unit tripping and inputting disturbance test, a wind power plant power change test, a disturbance test for reactive-load compensation equipment of the wind power plant, a tripping disturbance test for hydroelectric power plant and thermal power plant near the wind power plant and a manual single-phase ground short circuit test at the outgoing line part of the wind power plant, and records running curves of the wind power plant under each condition to finish the parameter test. The present invention realizes the advantage of providing precise measurement data for the stability analysis of an electric power system and the production dispatching of a power grid.

Method for testing dynamic model parameters of wind power plant

The present invention has disclosed an optimal control method for reactive voltage of wind power and photovoltaic power centralized grid connection in the field of wind power and photovoltaic power grid connection control technology, comprising: setting actuating stations used to control single wind power plant/photovoltaic power plant, setting substations used to control actuating stations and set master station used to control all the substations; master station calculates setting voltage reference Uof each substation; adopting 3&#x3c3; method to process set voltage reference Uto obtain set voltage reference interval; regulating high-side voltage of substation to make it fall in set voltage reference interval; if high-side voltage of substation does not fall in set voltage reference interval, then regulating the equipment in wind power plant/photovoltaic power plant via actuating station. The present invention guides the actual operations of electric power system.

Optimal control method for reactive voltage of wind power and photovoltaic power centralized grid connection

A static testing and calibrating method for PID link of control system of wind turbine includes following steps. A PID control link of the PID link of the control system of wind turbine is tested. A PID regulator response characteristics is tested. The PID link of control system is calibrated by applying test results of the PID control link and the PID regulation response characteristics.
