摘要
随着变电站设备智能化程度的不断提升,modbus通讯、光纤通讯的广泛应用,电力电子技术的发展,使变电站功能模块化设计成为可能。分布式模块化设计是变电站智能化设计、提高系统生产运维效率、降低运维成本的一个有效方式,分布式设计变电站将是变电站发展的一大趋势。文章就变电站直流电源系统方案中的传统集中式与分布式设计从系统方案、直流系统绝缘、级差配合、运行维护角度对比分析,探讨两者优缺点,给设计人员提供更多的方案参考。
With the increasing intelligence of substation equipment, the wide application of Modbus communication and optical fiber communication, and the development of power electronics technology, the functional modularization design of substation becomes possible. Distributed modular design is an effective way to intelligently design substation, improve the efficiency of system operation and maintenance, and reduce the cost of operation and maintenance. Distributed design of substation will be a major trend of substation development. This paper compares and analyzes the traditional centralized and distributed design of DC （direct current） power supply system in substation from the aspects of system scheme, DC system insulation, differential coordination, operation and maintenance, and discusses their advantages and disadvantages, to provide designers with more project reference.
