继电保护整定计算软件中的若干问题分析

详细研究了整定计算软件的现状,指出现有整定计算软件在计算结果的正确性、软件的实用性和可用性、软件的通用性和可发展性方面存在的问题,提出了解决的方法,即:(1)把整定计算用的运行方式分解为厂站大小方式、供电方式和检修规则三者的组合,不仅能简化设置缩小选择范围且能保证定值正确;(2)提供完整定值单的生成与管理,增加定值校正功能以加强软件实用性;进行严格的交互设计过程保证软件的可用性;(3)保证软件通用性采用插件式的软件结构通过功能模块的版本控制实现省级、地区级和县级三类用户共同的整定平台;(4)学习和实践软件工程的理论,加强软件开发的管理工作,提高软件质量,保证整定软件具有可发展性。

On some problems about protection setting calculation software

The status of setting calculation software is detailed.The problems are pointed out,such as the validity of calculation results,usability,universality and developability of software.The methods to solve these problems are four steps.First,it takes operating condition as the combination of running mode of plant or station,power supply topological and rules of equipment maintenance.It is useful at simplifying setup and choice of operating conditions and ensuring calculation result correction.Second,the functions of achieving integrated setting list is offered,setting examination and rectification are setting to enhance software's practicality and interaction design method is employed to ensure software's usability.Third,it introduces software structure with insert mode to actualize the common platform.With this structure,the software can be used in various levels of power networks by switching function groupware with corresponding edition.It is important to solve software' universality.Fourth,the theory of software engineering is studied and the management of development course is strengthened to ensure the developability of software.
