Research on visualized anti-accident inference system for ultra high voltage DC converter station based on PSCAD model

为了提升直流控制保护系统性能,保障大电网安全运行,同时使调度、运行及检修人员能够开展反事故演习,进一步提升其现场事故应急处置能力,本文建立特高压直流换流站PSCAD模型,对模型引擎与变电站仿真系统交互技术进行研究,并将现场运行人员工作站(OWS)系统应用于仿真系统。研究结果表明,通过建立PSCAD模型并进行仿真系统分析,可进一步实现对直流换流站设备进行故障模拟、录波回放及自动分析的功能。

In order to improve the DC control and protection performance,ensure the safe operation of large power grid,enable the dispatching,operation and maintenance personnel to carry out anti-accident exercises,and further improve their on-site accident emergency disposal ability,this paper establishes the PSCAD model of ultra high voltage(UHV)DC converter station,studies the interaction technology between the model engine and substation simulation system,and applies the on-site operator work station(OWS)system to the simulation system.The results show that by establishing the PSCAD model and analyzing the simulation system,the functions of fault simulation,recording playback and automatic analysis of the DC converter station equipment are further realized.
