The adaptive protective relays categorically sets up the math model and realized theory of adaptive relay protective settings calculation . the calculation of complex faults solves the computation of all kinds of faults involved in power network . the coordination of directional protective relays in multiloop networks solves the calculation of break points set and the coordination of main protection with backup protection 其中自适应定值计算和管理问题分类建立不同元件(线路)自适应继电保护定值计算的数学模型及其实现的理论;复故障计算问题解决了计算电网中各种故障(包括短路、断线)的计算问题;复杂环网的保护配合问题解决了大规模复杂环网断点的求取以及主/后备保护整定配合的问题。
At last , according to a actual power system relay values calculation case , which is realized on the basis of our theory , the validity and practicability of adaptive calculation and management are proved in practical production and operation of power . index terms : adaptive technology , protective relay setting calculation and management , complex fault , mutiloop network , the coordination of main protection with backup protection 最后,我们结合我们利用本文所介绍的理论实现的一个具体电力系统的定值整定计算和管理的实际例子,验证了利用自适应技术建立的继电保护定值计算和管理在实际电力生产和运行中的有效性和实用性。
The thesis uses sql server 6 . 0 database , standard sql access interface , and oriented - object program language vc + + to implement our electric network dispatching message management system . the system can operate like this : automaticly check if having data files come ; discriminate file type ; automaticly read data into database ; rapidly give out the precise analysis results , including waveform display , fault component calculating ; select fault phase ; distinguish fault type ; precisely fault allocate ; run all kinds of database administration , like antomatic add - on , automatic deletion , amendment , inquiry by different conditions ; print all kinds of outcome and keep them into database ; share data resource by web technique ; deal with complex faults . the whole system i finished will be powerful technic support for dispatching operation 本文采用标准的sqlserver6 . 0数据库,标准sql访问接口和面向对象编程工具vc + +进行编程,实现了集数据库、分析计算、图形化界面、网络通讯于一体的电网故障录波信息管理及故障诊断系统,该系统能够在每次故障后自动查询有无数据文件的到来;能够对传送到调度端的数据文件分析其类型;能够按comtrade格式自动地将大量数据信息完整地填入数据库中;能够进行故障选相,故障类型判别和故障精确定位;能够快速地对故障做出精确的分析,计算各次谐波分量,有无功和视在功率,功角,序分量等;能够对数据库进行各项管理,如浏览,自动添加和删除,修改和按各种不同条件进行查询;能够将计算结果,各种表格图形打印出来和保存进数据库中;能够将计算分析结果通过web技术为其他部门提供共享数据资源
Under the circumstance of complex fault , it is highly important how to do further diagnosis with the help of recorded fault data . a method of virtual protection is put forward , and the corresponding generally diagnostic model is established . this method effectively makes up the limitation of diagnosis with only switch and protection information 对在复杂故障情况下利用故障录波信息进一步诊断的方法进行研究,提出了虚拟保护的诊断思想,并建立了相应的综合诊断模型,有效地弥补了利用开关、保护信息诊断的局限性。
Based on system model , the article ulteriorly discusses a few issues of requiring the adaptive theory in relay protective settings calculation and management , such as adaptive relay protective settings calculation and management , complex fault calculation and coordination of directional protective relays in multiloop networks 在建立了系统结构的基础上,进一步详细探讨了继电保护定值计算和管理中需要自适应技术的几个主要问题,即:自适应定值计算和管理问题;复故障计算问题;复杂环网保护配合问题。
