摘要
防止供电系统出现越级跳闸现象是煤矿企业比较关心的问题。在对晋北煤业供电系统进行简要概述的基础上,基于GOOSE技术设计研究了防越级跳闸系统,系统分为管理层、通信层和间隔层3个层级,各层级发挥对应的作用实现防越级跳闸效果。对保护装置的主要硬件设施进行了分析,采用power PC+FGPGA方案进行数据的分析与处理,丰富了系统的功能和可靠性。将设计的防越级跳闸系统应用到晋北煤业供电工程实践中,将等待下级装置闭锁信号时间设置为20 ms,半年时间内出现4次供电故障,均未出现越级跳闸现象,实践效果良好。
To prevent the power supply system from tripping is a more concerned problem for coal mine enterprises. Based on the brief overview of the power supply system of Jinbei Coal Industry, the anti-override trip system is designed and studied based on GOOSE technology. The system is divided into three levels : management layer, communication layer and interval layer, and each level plays a corresponding role to realize the anti-override trip effect. The main hardware facilities of the protection device are analyzed, and the power PC + FGPGA scheme is used for data analysis and processing, which enriches the function and reliability of the system. The designed anti-overstep tripping system is applied to the power supply engineering practice of northern Shanxi Coal Industry. The locking signal time of the lower device is set to 20 ms.Four power supply faults occur within half a year, and no overstep tripping occurs. The practice effect is good.
