Wind power plant grid-connection performance monitoring method and system

Abstract

The invention provides a wind power plant grid-connection performance monitoring method. The method comprises the steps of acquiring equipment information and operation data of a wind power plant in real time based on a message bus; performing real-time monitoring on the grid-connection performance of the wind power plant based on the equipment information, the operation data and a pre-constructedgrid-connection performance evaluation system, wherein the grid-connection performance evaluation system comprises wind turbine generator grid-connection performance evaluation, reactive power compensation device grid-connection performance evaluation and whole station grid-connection performance evaluation. Real-time monitoring, analysis and evaluation are carried out through on-line measurementand calculation, the grid-connection performance is directly obtained, and technical support is provided for real-time supervision and optimized operation of the full-life-cycle grid-connection operation characteristics of the wind power plant. The method is simple, practical and easy to implement.

Description

technical field [0001] The invention belongs to the field of dynamic monitoring of electric power systems, and in particular relates to a method and system for monitoring wind power grid-connected performance. Background technique [0002] In order to ensure the safe and stable operation of the power system after large-scale wind power is connected to the grid, my country's wind power grid-connected standards put forward clear requirements for the grid-connected performance of wind farms, including power quality, active power control capabilities, reactive power and voltage control capabilities, low-voltage traversal ability, etc. At present, the main method for wind farm grid-connected performance evaluation is field test combined with offline simulation. Restricted by the operating conditions of the power grid, the on-site test period is long, and it is difficult to obtain the data of some working conditions, especially the strong wind condition; some parameters involved i...
