基于禁忌搜索算法的配电变压器经济运行

Economic Operation of Distribution Transformer Based on Tabu Search Algorithm

针对变电站配电变压器电能损耗严重的问题,提出一种利用禁忌搜索算法对配电变压器运行方式进行优化的方法,即利用禁忌搜索原理,以经济效益为目标函数,对变电站两台及以上配电变压器的备选投切点进行优选,从而获得配电变压器运行方式的最优控制策略,并通过MATLAB编程对算例进行验证。结果表明,该方法可减少配电变压器的电能损耗,具有良好的经济效益;此外,该方法还约束了投切次数,可避免设备频繁投切造成的电力系统安全隐患。

Electric energy loss of distribution transformer in power substation has been a serious problem. To solve this issue, this paper proposes the use of tabu search algorithm to optimize the operation mode of distribution transformers. At first, the article sets the economic benefit as objective function. And then it works out the best control strategy hy tabu search from muhiple alternatives for distribution transformer in power substation. Finally, this method is verified by MATI,AB programming. The results show that the method can reduce power loss of distribution transformer with good economic benefits; moreover, the number of operation were restricted to avoid safety hidden danger of power system caused by frequently on off switch of the device.
