直挂SVG电网适应性RTDS测试技术研究

Research on RTDS-based Power Grid Adaptability Test Technology of Suspended SVG

传统中高压大容量直挂式静止无功发生器(SVG)电网适应性测试存在成本高、效率低、周期长的问题,研究采用基于实时数字仿真器(RTDS)的直挂SVG电网适应性测试技术,建立面向直挂SVG的RTDS电网适应性试验平台并开展电网适应性测试,具有快速、低成本、可重复性开展试验等优点。试验结果表明:该平台可以对SVG电网适应性性能开展测试验证,可以加快SVG产品的优化及选代升级速度。

The traditional grid adaptability test method for suspended medium-high voltage and large-capacity static var generator(SVG)has the disadvantages of high cost,low efficiency and long cycle.To solve the existing problems,a power grid adaptability test technology of suspended SVG based on real-time digital simulation(RTDS)is studied and then a RTDS-based hardware-in-the-loop test platform is established and the grid adaptability test is carried out.This method has the advantages of fast,low cost and repeatability.The test results show that the platform can test and verify the power grid adaptability of SVG and can speed up the optimization and iterative upgrade of SVG products.
