摘要

提出了一种先进的考虑高频发电跳闸和低频减载的脱阶保护仿真平台。在该仿真平台中，采用实时数字模拟器(RTDS)作为实时电力系统模拟器。通过高速I/O卡，将实际工业OOS分裂保护装置集成到所提出的仿真平台中。基于中国南方电网的实际控制策略，对高频发电跳闸和低频减载组件进行了仿真建模。在RTDS中对CSG真实网格进行建模，进行实时半实物仿真。仿真结果表明，有高频产生脱扣结果与无高频产生脱扣结果存在明显差异。

Advanced Out-of-Step Splitting Protection Simulation Platform with Considering High Frequency Generation Tripping and Low Frequency Load Shedding

This paper presents an advanced out-of-step (OOS) splitting protection simulation platform considering high frequency generation tripping and low frequency load shedding. In the proposed simulation platform, Real-Time Digital Simulator (RTDS) is utilized as the real-time power system simulator. Through the high-speed I/O card, real industry OOS splitting protection device is integrated into the proposed simulation platform. Based on the real China South Power Grid (CSG) control strategy, high frequency generation tripping and low frequency load shedding components are modelled in the simulation. CSG real grid is modelled in the RTDS to perform the Real-time hardware-in-the-loop simulation. Simulation results present that there is a clear difference between with high frequency generation tripping results and without high frequency generation tripping results.
