摘要
为解决大容量光伏电站的远距离并网问题,分析了光伏电站运行机理及两端MMC-HVDC系统的输电原理,设计了适用于光伏电站接入的MMC-HVDC启动控制策略,有效抑制了启动过程中的冲击电压,实现了光伏电站的可靠并网。基于RTLAB实时仿真平台建立了光伏发电系统经两端柔性直流输电系统并网模型,验证了算法的正确性。
In order to solve long - distance integration of large capacity PV power station to power grid, this paper analyzes the operation performances characteristics of the photovohaic power plant and the transmission principle of the MMC - HVDC, designs the startup strategy for PV power plants integrated into grid using MMC - HVDC, which effectively inhibits impulse voltage during startup and realizes the reliable integration. Using real- time simulation platform based RTLAB, it establishes the model of transmission system integrated into grid using MMC - HVDC and verifies its correctness.
