摘要

首先在分析构网型直驱风电机组功角与电流暂态特性的基础上

阐释功角失稳与过电流的产生机理及其相互影响。由此提出一种计及功角稳定与故障限流的暂态协调控制策略

通过在构网控制的有功环路中构建不平衡功率补偿量以抑制功角增加

同时依据电流不越限目标整定无功指令以限制过流出现。不同暂态电压跌落深度的构网型直驱风电机组仿真测试以及与其他暂态控制策略相比

结果表明所提协调控制策略能有效抑制风电机组功角增加及失稳问题

并将输出的故障电流限制在允许范围内

可确保构网型直驱风电机组的稳定性和安全性。

Abstract

Based on the analysis of the power angle and current transient characteristics of the grid forming-permanent magnet synchronous generator （GFM-PMSG）

this paper explains the mechanisms behind power angle instability and overcurrent

as well as their mutual influence. A transient coordinated control strategy considering power angle stability and fault current limiting is proposed. The unbalanced power compensation is constructed in the active power loop of the grid forming control to suppress the increase in the power angle

while the reactive power command is adjusted to meet the current limit target

thereby limiting overcurrent. Simulation tests of the GFM-PMSG with different transient voltage drop depths

along with comparisons to other transient control strategies

show that the proposed coordinated control strategy can effectively suppress power angle increase and wind turbine instability. Additionally

it limits the output fault current within the allowable range

ensuring the stability and safety of the GFM-PMSG.
