【摘要】 煤矿供电网络是保证煤矿安全生产的重要前提,在国民经济各部门和人民日常生活中也占有特殊地位。因此对煤矿供电网络进行可视化潮流分析,这对运行中发生的问题做出对策,对线路进行改造或对电网进行重新分配,优化电网,减少电网的损耗,保证供电网络的安全经济运行,提高煤矿供电公司经济效益是必不可少的。本文所研究的是煤矿供电网络的可视化潮流分析系统。主要是在潮流计算的相关解法及基本数学模型的基础上作了改进,提出了一种新的可视化潮流分析系统。本文采用MATLAB编写潮流计算程序,使得计算更符合实际,加快了计算速度;同时还采用了国内外先进的专用电力系统潮流仿真分析软件PowerWorld,使得潮流计算与可视化图形相结合,并且还对电网的实时运行情况进行了监测;最后以电气电子工程师协会提出的标准5节点系统(IEEE-5节点)供电网络和双鸭山60kV煤矿供电网络为例进行可视化潮流分析。更多还原

【Abstract】 The coal mine power network is the important premise of guaranteeing the safe production of coal mine, and also occupies the special position in each section of national economy and people’s daily life. Therefore, it is an essential to analyzing of visualization load flow to the coal mine power network, doing countermeasures towards to the problem circulate in the operation, rebuilding to the circuit or redistributing to the electric network, optimizing power network, reducing wastage of the electric network, insuring the operation of safety and economy to the power system, improving economic benefits of the coal mine power company.This paper introduces the new visualization load flow calculation system, which on the basic of load flow calculation mathematic model and relative solving method, and the calculation method has been improved appropriately. This paper compiles load flow calculation program in MATLAB, the result we get will more correspond to reality, and the calculation will speeds up. At the same time, this paper also adopts the expert electric power system load flow simulator–PowerWorld, which is the domestic and international advanced software. This software integrates load flow calculation and visualization drawing system, and monitors the real time operation of power network also. At last as a sample, this paper visually analyses load flow in IEEE-5 power network and Shuangyashan 60kV power network.更多还原
