基于可视化技术的配网保护定值整定原则智能化配置

Intelligent Configuration of Setting Principle of Distribution Network Protection Based on Visualization Technology

整定计算是保障当今电网安全运行的基础性工作,在配电网范围内,任何设备的投运和使用都离不开整定计算的工作。而对于不同类型不同位置的开关设备,每一种都有其特定的整定原则,都需要根据相应的整定原则进行出单;在整定原则中,有着不同的保护方式,每一种保护方式都对应着不同的计算方法,整定计算工作人员在进行整定工作时需要对不同设备进行规则的选取,合理应用不同的保护方式对相关设备进行保护,但在对众多规则的选取中,人工整定存在着相对误差,容易造成保护方式不得当而使得电力系统的安全性、可靠性降低。文章提出的系统对相关的整定原则进行了分类和整理,并且通过系统实现了不同设备规范地对应了不同的整定原则,不仅使配网的整定原则得到整理,同时使得配电网的整定原则得到灵活配置。

Setting calculation is the basic work to ensure the safe operation of power grid today.In the scope of distribution network,the operation and use of any equipment are inseparable from the work of setting calculation.For different types and different positions of switchgear,each has its own specific setting principle,which needs to be issued according to the corresponding setting principle;in the setting principle,there are different protection modes,each protection mode corresponds to this different calculation method,and the setting calculation staff need to select the rules for different equipment when setting The principle of the application of different protection methods to protect the relevant equipment,but for many rules selection,there are relative errors in manual setting,which is easy to cause improper protection methods and reduce the security and reliability of the power system.The system proposed in this paper classifies and sorts out the relevant setting principles,and realizes different equipment specifications through the system It not only arranges the setting principles of distribution network,but also makes the setting principles of distribution network flexibly configured.
