继电保护定值在线整定软件开发与实践
|
摘要
继电保护装置对电力系统的安全稳定运行至关重要,而保护装置定值的准确性依赖于保护定值整定软件对电网的各种运行方式及各种故障进行反复而周密的计算,由于电网实际运行方式往往超出了离线整定方式,这就使得当前基于离线模式的整定计算软件难以确保定值的准确性。文章提出并开发了一个新的继电保护定值在线整定软件,依托基于云和瘦客户端的在线整定计算技术和基于多线程和云计算的分布式并行计算架构,主要功能模块有图形建模、参数计算、在线整定和系统管理,成功实现了继电保护定值在线整定。所开发软件已在实际电网现场成功投运,具有良好的实用性。
Relay protection devices are critical to the safe and stable operation of the power system,and the accuracy of the protection device's setting value depends on the protection setting value setting software for repeated and careful calculation of various operating modes of the grid and various faults. The actual operation mode often exceeds the offline setting method,which makes it difficult to ensure the accuracy of the current setting calculation software based on offline mode. A new on-line relay protection setting software is proposed and implemented. Rely on online tuning technology based on cloud and thin clients,distributed parallel online tuning computing architecture based on multi-threading and cloud computing,The main function modules are graphical modeling,parameter calculation,online setting and system management. We achieve the goal of on-line relay protection setting. The software has been applied in practical power network successfully,which shows a good practicality.
