摘　　要：作为“发电厂安全稳定紧急控制装置的研制———原理及算法”的续篇,主要介绍了WAW1型安全稳定紧急控制装置的实现技术及动模试验结果。装置以分层分布式多CPU系统模块构成,以公用内存方式实现高速通信,以软硬件配合解决多CPU系统的同步采样、同数据窗计算和同步计算状态转换的技术问题。动模试验结果表明,装置能够跟踪发电厂送出线运行方式、运行状态的变化,线路过负荷正确报警。系统故障时能正确预测暂态稳定性并快速投入切机措施保证系统不失稳。对于动态不稳定,装置能正确检出失步并起动解列,达到了预期的控制要求。It mainly introduces the implementation technology and the physical simulation of WAW?1 power System security Emergency Control Equipment.The equipment is of multi CPU distributed and hierarchic system. It uses common memory to realize high speed communication, solves the technical problems of in phase sampling and state switchover of same data window calculation and synchronous calculation in the multi CPU system by both software and hardware. The physical simulation results show that the equipment can follow the run state change of power plant feeders, alarm correctly when line overload occurs; forecast transient stability correctly when fault occurs and put in off load measures to prevent system instability. The equipment can check up synchronization loss and start up disconnection when power system dynamic instability occurs, which meets the expected control demand.
