摘要
基于目前普遍采用的电磁暂态仿真工具PSCAD/EMTDC,根据实际工程软件进行了直流控制保护系统仿真平台的二次开发。分析了直流控制保护工程软件在工控机中的分时处理、中断计算过程及其在PSCAD/EMTDC中的等效实现方法,利用该仿真平台进行了灵宝扩建背靠背直流工程的控制系统建模。将基于本平台搭建的电磁暂态模型与实际工程系统调试时的电流阶跃响应结果进行了对比,证明该平台与工程实际控制保护系统功能等效。基于该平台进行直流工程控制系统仿真的结果可信,对于广泛开展跨区直流输电系统的电磁暂态仿真研究具有工程实际指导意义。
This paper describes the secondary development of HVDC control and protection system simulation platform based on the actual engineering software and the currently widely used electric magnetic transient simulation tools PSCAD/EMTDC. This paper analyzes the time interrupt and Task/Proc scheduler mechanism of actual control and protection application software which operates on industrial control computer, as well as its equivalent simulation method in PSCAD/EMTDC. The simulation platform is used to build the control system model of Lingbao II BTB HVDC project. Comparing the new electric magnetic transient model with DC current step response result of simulation and on-site commissioning, it is found that the simulation platform has an equivalent function of the actual control and protection system. The simulation results based on the new designed simulation platform are credible, which has guiding significance for extensively carrying out the electric magnetic transient simulation of inter-district HVDC transmission system.
