适用于链式SVG的半实物实时仿真平台搭建及功能验证

Construction and Function Verification of a Hardware-in-loop Real-time Simulation Platform for Chain SVG

采用物理试验平台对链式静止无功发生器(SVG)装置整机功能验证,存在建设周期长、风险成本高等缺点,而采用半实物实时仿真技术对SVG装置整机功能进行验证,可以缩短装置调试周期,并且风险可控,试验成本低。为此,在RTDS实时仿真系统小步长模块中搭建了SVG半实物实时仿真平台,并基于该平台对SVG装置的低电压穿越、系统频率偏移等新功能进行了验证。平台的搭建为SVG装置的新功能、新算法验证奠定了基础,同时对SVG设备制造厂商的技术研发也具有一定的借鉴意义。

There are disadvantages such as the long construction period and high risk cost in the verification of the whole equipment function of the chain static var generator(SVG)by physical test platforms,while the verification based on hardware-in-theloop real-time simulation technology can shorten the debug period of the equipment,control the risk and reduce the test cost.For that reason,an SVG hardware-in-the-loop real-time simulation platform is built in the small step module of RTDS real-time simulation system,based on which new functions of the SVG equipment including the low voltage traversal and system frequency offset are verified.The platform built lays a foundation for the verification of new functions and algorithms of the SVG equipment and at the same time has a certain significant reference to the technical research and development of SVG equipment manufacturers.
