摘　　要：为了避免合环运行的潮流穿越问题,贸易结算的计量点设置在各台受电变压器高压侧,用户在正常工况下,基本电费没有问题,但是对于用户受电设备检修等需要倒闸操作的工况,电能表直接计量的最大需量不能准确反映用户对电网的负荷需求,很有可能造成用户当月的基本电费翻倍的情况,造成用户的利益受损。为了响应企业的合理诉求,优化营商环境,对于电力用户在一些特殊的工况下,用户实际使用的最大需量的准确计量十分必要。为此,对于大型电力用户这种特殊的用电计量方式,文章基于用电负荷曲线,对其结算周期内的最大需量的计费提供了两种估算方法。In order to avoid the tide crossing of closed-loop operation,the measurement points for trade settlement are set on the high-voltage side of each transformer.Under normal working conditions,there is no problem with the basic power rate.However,for conditions that require switching operations such as maintenance,the maximum demand directly measured by energy meters cannot accurately reflect the load demand of users on the power grid.It is quite possible to double the basic power rate for that month,causing loss to the interests of the users.In order to respond to the reasonable demands of enterprises and optimize the business environment,it is necessary to accurately measure the maximum of the actual demand of users under some special working conditions.Therefore,for the special electricity consumption mode of large power users,this paper provides two estimation methods for the maximum demand based on the power load curve in the settlement period.
