摘要

风电场运行过程中常有并网点（point-of-common coupling

PCC）电压与功率因数无法同时兼顾的控制问题。本文对装有风速前馈控制的恒电压控制进行改进

在其基础上增加了无功限幅环节

并基于有功预测层和无功控制层分层处理方式

提出了改进恒电压控制和恒功率因数控制相结合的联合控制策略

该控制策略根据风机实际运行时有功功率、无功功率的大小

计算出联合控制主导因子

并依据联合控制主导因子的变化情况

进行控制策略调整。利用电力系统分析综合软件（power system analysis software package

PSASP）建立了WSCC9节点系统模型

对系统控制策略进行了仿真验证

结果表明联合控制策略既能保证PCC节点电压的稳定

又能同时保证机组较高的功率因数。

Abstract

During the operation of a wind farm

there is often a control problem in which the voltage and power factor of the point of common coupling（PCC） cannot be considered simultaneously.In this paper

the constant voltage control with wind speed feed forward control is improvedand the reactive power limiting link is added.The joint control strategy of combining the improved constant voltage control and constant power factor on the basis of active prediction layer and the reactive control layer layered processing mode.The joint control dominant factor is calculated in accordance with the active and reactive power magnitude of the actual operation of the fan

and adjust the control strategy according to the change of the joint control dominant factor.The WSCC9 node system model is established by using power system analysis software package（PS ASP）

and the system control strategy is simulated and verified.It is shown by the result that the joint control strategy can ensure not only the stability of the PCC node voltage

but alsothe higher power factor of the unit.
