煤矿35 kV变电站微机保护系统设计与实施

Design and Implementation of Microcomputer Protection System for 35kV Substation in Coal Mine

煤矿35 kV变电站是煤矿配电网络中的重要部分,承担着保证煤矿供电质量、维护煤矿供电可靠性的重要任务。结合煤矿供配电系统的特点,以msp430作为核心,设计35 kV变电站的微机保护系统,实现煤矿变电站继电保护的自动化和综合化。针对施工过程中可能存在的干扰源,提出抗干扰措施,增加微机保护系统的稳定性。

The 35 kV substation in coal mine is an important part of the coal mine distribution network, and it is an important task to ensure the quality of coal mine power supply and maintain the reliability of coal mine power supply. Based on the characteristics of coal mine power supply and distribution system, It used msp430 as the core to design the microcomputer protection system of 35 kV substation to realize the automation and integration of relay protection in coal mine substation. For the possible interference sources during the construction process, anti-interference measures are proposed to increase the stability of the microcomputer protection system.
