Technical Performance Test and Improvement Measure Study for Dynamic Reactive Compensation Devices Applied in Large-Scale Wind Power System

风电场配置动态无功补偿装置可以有效提升风电汇集地区无功电压控制水平,但实际运行中,无功补偿装置存在运行可靠性差、动态响应时间不满足要求等问题,未能有效发挥其动态无功支撑能力。通过开展无功补偿装置性能检测,针对检测中发现的运行可靠性差、动态响应时间不满足要求、电能质量不合格等问题提出有效的整改措施。实践表明,通过开展无功补偿装置性能检测,可有效提升装置技术性能,保障风电汇集系统安全稳定运行、提升风电消纳能力。

The voltage stability problem of large-scale wind power collection system is key factor to power grids. Dynamic reactive power compensation devices on wind farms are effective for controlling reactive power and voltage of wind power system. However, in field operation process, reactive power compensation device has problems including unreliable operation, slow dynamic response time which does not meet power grid requirement. Some effective correction measures are proposed based on testing results. Practice shows that reactive power compensation device performance testing and rectification work can effectively improve device performance, system operation safety and wind power accommodation capability.
