同煤电网优化设计

摘要

同煤电网由于设备陈旧，电网负荷分配不合理，不仅处于较差的运行状态下，而且存在着安全隐患，对电网进行优化已经势在必行。设计首先叙述了同煤电网的概况，在收集了数据的基础上对同煤电网建立模型，并且将这些数据录入至PSASP7.0中，制作出系统的单线图，建立电网的基础数据库，并且模拟多种不同运行方式建立相应潮流分析的方案进行潮流分布计算，得出合理结果后将其作为分析的数据基础。通过对潮流计算结果分析后找出电网运行中的不合理和薄弱环节，最后根据各种方式计算电网各种运行方式下的损耗，重点分析问题严重的几个变电所，提出解决方法，分析和总结出可行的调整方案并从经济角度进行对照，进行可行性分析，最后得出优化后电网的运行状况，总结被改善的环节。

Abstract

Datong Coal Mine Group Power Grid as a result of obsolete equipment, unreasonable load distribution, the operation not only in poor condition, but also there is a security risk ,the power grid must be optimized. First the design describe the overview of Datong coal industry group power grid ,build the model of Datong coal industry group power grid based on the collection of data, and entry these data to PSASP7.0, to establish the single system map, the basic database for grid, and simulate different methods of operation to establish the corresponding plans of power flow calculation and execute the calculation, the reasonable results will be the data basis of analysis. The results of trend analysis to identify unreasonable and weak parts in the operation of the power grid, and finally based on a variety of ways of calculating and the power grid loss under various operating mode, analysis of several substation problems, make propose solutions, analyze and summarize the possible adjustment programs and control from an economic point of view, to conduct a feasibility analysis, came to the conclusion that the optimized operation of the grid, summing up the part improved.
Keywords: Datong Coal Industry Group Grid; Power Flow Analysis; PSASP7.0;
