摘要
重点介绍了相比于贵广Ⅰ回的控制保护系统,贵广Ⅱ回在硬件和软件工程上的改进,包括极控系统、站控系统、直流保护、直流滤波器保护、交流滤波器保护系统。其中硬件工程同样基于SIEMENS公司的高速数字化可编程控制系统SIMADYN D和SIMATIC S5,在设计上没有大的改动,只是从运行维护方面考虑,改进了屏柜间硬接线部分;软件工程采用STRUC G和STEP 5(对6MD66单元编程采用DIGSI),增加了一些控制功能,消除了贵广Ⅰ回运行维护中暴露出来的缺陷。
The upgrade of C＆P systems adopted in Gui-Guang Ⅱ HVDC project is presented, comparing to Gui- Guang Ⅰ HVDC project. Pole control, station control and DC protect systems are expatiated. The hardware project used in Gui-Guang Ⅰ is realized with the high speed digital multi-microprocessor system SIMADYN D and SIMAT- IC S.5 of SIEMENS, the design is almost same, only hard circuit between cubicles is improved for maintenance. In software project, the SIMADYN D system is configured with STRUC G, which is a graphical editor and suitable for configuration, diagnosis and documentation. The software of SIMATIC S.5 system is written in the STEP5 programming language, which is specially designed for control tasks, and for the 6MD66 bay control units the software DIG- SI is used. Some control functions are added for avoiding bugs which are discovered during operation of Gui-Guang Ⅰ HVDC project.
