摘要
用传统电网络理论,以灵敏度矩阵的形式建立了故障诊断方程,再结合能量最低原理建立利用优化方法中的BFGS变尺度法求解各段导体电阻增量的数学模型,然后利用VC编程开发了可视界面友好且使用方便的接地网诊断软件系统。通过仿真计算和模拟试验证明了该诊断系统的实用性和可靠性。
Making use of the traditional electric network theory, the fault diagnosis equation is set up in the form of sensitivity matrix Associating with the lowest energy theory as well as the BFGS variable metric method, mathematic model which solves the resistance increment is established; based on all of the above means, the diagnosis system about the corrosion and the broken point of the grounding grid is developed by means of VC. The diagnosis system is convenient to use, and its interface is very friendly to the user. Primary emulation calculation and simulation experiment achieves good effects.
