摘要

近海风电场接入本地电源支撑不足的地区配电网时

风电出力波动引起的系统电压波动将是主要制约条件。文中研究近海风电场接入对地区电网电压波动的影响。首先

针对风电场定功率因数和定电压两种无功控制模式

推导了风电功率波动与接入点电压波动的量化关系。在此基础上

基于电压允许波动范围约束

建立了风电接入规模与节点短路容量的函数关系。在PSCAD／EMTDC中搭建近海风电场并网系统模型

对不同系统短路容量下风电场的最大并网容量进行了仿真测试

并与理论推导进行对照。最后通过珠海桂山风电场实际工程的仿真测算验证了模型的有效性。

Abstract

When offshore wind farm is connected to a distribution network lack of local generation

the voltage fluctuation caused by the wind power will become prominent. This paper studies the impacts of offshore wind farms on the voltage control of main network. For both constant power factor and constant voltage control modes

the relationships between the wind power capacity and the voltage fluctuation of the main grid are set up. Then the maximum capacity of offshore wind farms constrained by the permitted voltage variation range is calculated. In order to verify the theoretical analysis

a simulation system was built with EMTDC/PSCAD to study the maximum capacity of the wind farm under different short-circuit capacity of point of common coupling (PCC). Tests with a real life project

Guishan offshore wind farm

are presented in the end of the paper. This work is supported by National Basic Research Program of China (973 Program) (No. 2012CB215104).
