以保护定值的在线校验和仿真为应用背景,详细叙述了继电保护数据库建模中遇到的主要技术难点和相应的解决方案。综合考虑了模型的通用性、维护工作量、数据库容量和访问效率等多个相关因素,力求达到保护数据建模的整体性能最优。对整个电网建立了完整统一的一次和二次设备模型。基于整个电网的统一模型,实现了面向实际成套保护装置的图形化建库和保护装置与相应一次设备的图形化关联。应用结果表明,该保护建模方法设计合理,具有良好的应用前景。
In order to protect the value of the online calibration and simulation as the application background, a detailed description of the main technical difficulties encountered in the modeling of relay protection database and the corresponding solutions. Comprehensive consideration of the model of versatility, maintenance workload, database capacity and access efficiency and many other relevant factors, and strive to achieve the overall performance protection data modeling the best. For the entire power grid to establish a complete and unified primary and secondary equipment model. Based on the uniform model of the whole power grid, a graphical relation between the graphical warehouse and the protection device and the corresponding primary device for the actual complete protection device is realized. The application results show that the protection modeling method is reasonable in design and has good application prospects.
