10KV配电变压器二次侧无功补偿后的节电计算

Power saving calculation of reactive power compensation on the two side of 10KV distribution transformer

分析了在保证电力部门规定的高压供电的工业用户功率因数的要求下进一步节电的可行性和必要性,以公司选厂1#浮选变压器二次侧低压配电室采取低压集中无功补偿为研究对象,笔者利用现有的相关理论知识,可靠地提出了变压器二次侧投入低压无功补偿之后10KV高压供电线路和配电变压器的节电计算方法。利用此方法计算出无功补偿后节电的数值,为公司提供了可靠的无功补偿装置投资做出决策依据。

This paper analyzes the industrial users in ensuring the power factor of high voltage power supply electric power department under the requirements of the necessity and feasibility of further power saving, to plant two No. 1 transformer secondary side flotation of low voltage power distribution room adopt low voltage centralized reactive power compensation as the research object, the author uses the theory of existing knowledge, reliable forward after the two side of the transformer input low voltage reactive power compensation power saving IOKV high voltage power supply circuit and the calculation method of distribution transformer. Using this method, the value of power saving after reactive power compensation is calculated, which provides reliable decision-making basis for the investment of the reactive power compensation device.
