摘要
提出了一套可控串联电容补偿TCSC(Thyristor Controlled Series Compensation)动态模拟装置的设计方案。装置分为控制保护、录波和远程监控3个单元,每个单元中的插件都是一个完成单一任务的功能模块,各功能模块均是由双口RAM交换接口进行数据交换,通过工控机的ISA总线相连组成一个整体,采用这种硬件结构装置的实时性、可靠性和扩展性得到了极大的提高;控制保护单元和录波单元通过集线器与远程监控单元相连,同时控制保护单元和录波单元也有各自的监控界面,方便进行就地调试和监控。装置采用分层设计,中上层控制策略用C语言编程实现,易于进行各种控制策略和保护的研究。利用所研制的实验装置,分别在电容电压同步方式和线路电流同步方式下,进行了TCSC的基频阻抗特性实验。实验结果表明,该TCSC实验装置能够快速调节阻抗,并能灵活地完成不同阻抗模式之间的切换。
A design of TCSC（Thyristor Controlled Series Compensation） dynamic simulation equipment is presented,which includes the control ＆ protection unit,recording unit and remote monitoring unit. Each function module of unit performs a unitary task and exchanges data with each other via dual -port RAM. All function modules are integrated together via ISA bus. With the designed hardware structure,the real time performance,reliability and extendibility of equipment are greatly improved. The remote monitoring unit communicates with the control ＆ protection unit and recording unit through Hub for remote monitoring,while the control ＆ protection unit and recording unit have their own interface for local control ＆ monitoring and commissioning. Hierarchical structure is applied and the control strategies of middle and top levels are programmed with C for convenient study of various control strategies. With the developed equipment, the base frequency impedance characteristics of TCSC are analyzed with the line current and capacitance voltage as its synchronization signal respectively. The experimental results show that,the impendence can be rapidly adjusted and different impendence modes flexibly switched.
