摘 要:为实现对基于电网换相换流器(LCC)拓扑结构的直流输电换流站的有效控制和监视,文中设计了一种基于VxWorks嵌入式平台开发的全数字化通讯接口直流输电极控系统。该系统采用Vx Works嵌入式实时操作系统开发应用程序,并实现了PIC闭环控制算法和自动控制选择功能,可实现对换流站进行百微秒级周期的实时控制和监视。此外,该系统采用Profibus、IEC 60044-8—2002及GOOSE等数字通讯协议,实现了对外接口完全数字化的高可靠性控制设备。该控制系统可应用于中低压直流输配电领域,经过±20 k V/50 A背靠背直流输电系统模型的性能试验验证,满足数据传输实时性、可靠性需求和控制规范要求。For achieving effective control and monitoring of DC converter station based on LCC topological structure,a kind of DC transmission pole control system with full digital communication interface based on embedded platformVx Works is designed in this paper.This system adopts the Vx Works embedded real-time operating system develop-ment application program and implements the PIC closed-loop control algorithm and automatic control selection func-tion,which can achieve real time control and monitoring of period up to a hundred microseconds level for the convert-er station.Moreover,the system also adopts such digital communication protocols as Profibus,IEC 60044-8—2002 and GOOSE to achieve the highly reliable pole control equipment with fully digitalized external interface.The controlsystem can be applied to the fields of medium and low voltage DC transmission and distribution field and can,afterperformance test verification of a 50 A±20 k V back-to-back DC transmission system model,meet the real-time andreliability requirements of data transmission and the system control specification.
