Abstract

In this paper, dynamic performance of wind farm comprising of three Squirrel Cage Induction Generators (SCIG) is analyzed for grid connected operation. Wind integration causes power imbalances and power system dynamics leading to system instability. The SCIG based wind turbine requires reactive power for magnetization which causes shortage of reactive power in distribution system and hence causes losses that lead to instability of power system. The behavior of the system is analyzed with variation in wind speed, unbalanced and nonlinear loads and three phase fault. The DSTATCOM is being used to improve the performance of wind farm as per the standard of grid code. The grid code demands that power plant of any kind should support electricity network throughout their operation. The performance enhancement mainly involves the power quality issues and grid stability and fault ride through (FRT) capability. A complete power balance analysis of the proposed system is presented under different operating conditions.

配电网静态补偿器对风电场性能的提高

本文分析了由3台鼠笼式感应发电机组成的风电场并网运行时的动态性能。风电并网会导致电力不平衡和电力系统动态，从而导致系统不稳定。基于SCIG的风力发电机组需要无功功率进行磁化，导致配电系统无功功率不足，从而造成损失，导致电力系统不稳定。分析了系统在风速变化、不平衡和非线性负载以及三相故障情况下的运行特性。DSTATCOM被用于按照电网规范标准提高风电场的性能。电网规范要求任何类型的发电厂在其运行过程中都必须支持电网。性能提升主要涉及电能质量问题、电网稳定性和故障穿越能力。对系统在不同工况下的功率平衡进行了完整的分析。
