变电站综合自动化系统的应用研究

通过对变电站综合自动化系统应用现状的研究,指出常用的RS422/RS485接口总线和现场总线存在实时性、可靠性、兼容性差等问题.同时,指出在应用中二次系统频繁出现误报警、误动作等现象,需通过硬件和软件的方法实施各种抗干扰措施.针对不同的电压等级要求建立新的防误操作系统,加强设备状态检修管理,尽快建立适应综合自动化变电站运行管理的新规程.

Research into Application of Integrated Automation System of Transformer Substations

The research into the application of integrated automation system of transformer substations indicates that functions of real time,reliability and compatibility in the widely used RS422/RS485 mouth general line and present general line were found unsatisfactory.Besides,this paper argues that frequent mistakes of false alarming and misoperation,in practice,in a quadratic system can be avoided by dint of implementation of anti-jamming measures of both hardware and software.To meet this demand,this paper proposes: establishment of new systems of mistake-avoiding operation according to different voltage levels;strengthening of examining and repairing of equipment;laying down new criterion for integrated automation system of transformer substations as soon as possible.
