当前,工农业用电大幅度递增,电网容量偏小引起电压波动幅度大,成为工矿企业用电中一个非常突出而普遍的问题,大部分工矿企业的主要变压器为普通电力变压器,不但调压范围小,而且在电网电压波动频繁的情况下无法进行调压,甚至严重地影响了正常生产,如何从本单位的实际出发,因地制宜,多、快、好省地解决工矿企业的有载调压问题,就成了当前供用电工作中急需研究的一个重要课题。电力系统中可采用的调压方式是很多的,应用领域往往要通过技术经济比较后才能确定。根据工矿企业电网的特点,除极少数偏远地区由孤立电厂供电的厂矿可采用最为经济的改变发电机端电压进行调压外;对于绝大多数工矿企业来说,它们的特点是
At present, the industrial and agricultural electrical power increased dramatically, the grid capacity is too small caused by voltage fluctuations, as a very prominent and common problem in industrial and mining enterprises in electricity, most of the major industrial and mining transformers for ordinary power transformers, not only the pressure range Small, but also in the case of frequent fluctuations in grid voltage regulation can not be carried out, and even seriously affected the normal production, how to proceed from the reality of the unit, according to local conditions, more, faster and better provincial industrial and mining enterprises to solve the problem of on-load voltage regulator , It has become an urgent issue for the urgent need of electricity for work. Power system voltage regulator can be used in many ways, applications are often through technical and economic comparison can be determined. According to the characteristics of power grids of industrial and mining enterprises, factories and mines powered by isolated power plants, except for a few remote areas, can use the most economical way to adjust the terminal voltage of the generator for voltage regulation. For most industrial and mining enterprises, they are characterized by
