继电保护整定计算软件的通用性研究

A Study on the Universality of the Protection Setting Calculation Software

在介绍继电保护整定计算软件一般功能组成的基础上,从运行方式组合、阶段式保护配合计算、保护装置定值项整定计算和定值通知单4个方面对整定计算软件的通用性问题进行了详细探讨,指出将整定原则的可选性与整定原则的自定义相结合是解决整定计算软件通用性问题的一个很好的途径。另外,给出了基于VBScript和Excel技术的通用继电保护整定计算软件的整体解决方案,采用该方案开发的继电保护整定计算软件可大大减小软件维护的工作量,具有很强的通用性和可扩展性。该系统已成功应用于多家省网级和地区级电力系统继电保护部门,应用效果良好。

On the basis of a description of the common functional composition of the protection setting calculation software, the universality of the software is discussed in detail from the viewpoint of power system operating conditions combination, step relay coordination, protective device setting calculation and relay setting listing. It is pointed out that the combination of the optional principle and the user-defined relay setting calculation principle is a good way to solve the universality problem. Besides, an integral solution based on VBScript and Excel technology for the universal protection setting calculation software is proposed. The software developed based on the proposed scheme can greatly reduce the maintenance workload and is capable of good universality and expandability. It is being successfully applied in the relay protection departments of many power companies.
