针对目前应用的IC卡预购电系统中传递信息出现的不读卡、信息出错等故障情况,本文设计了利用计量自动化系统低压集抄模块功能对欠费的低压用户进行无卡式预购电的管理方案,由客户端、服务器、集中器、采集器和电能表交互处理数据构成无卡式预购电管理系统,实现远程用电控制、远程抄表、远程监测等功能。该系统的应用缩短了抄表周期,避免了因工作量大而导致的时差电量现象,有利于实时线损计算。该方案有效快速对拖欠电费用户进行跟踪管理,提高电费回收率,使得整个系统应用置于电力公司的控管之下。 相似文献

In order to guarantee the rapid sustainable development of the social economy, the power grid will make large investments in the construction of smart grids, the renewable energy network, the construction of long-distance transmission grid channels as well as the technology and service innovation of the power grid. According to the electricity transmission and distribution tariff accounting mechanism of costs and benefits, the power grid investment needs to be recycled by the transmission and distribution tariff. However, at present, the low electricity transmission and distribution tariff in China, which is based on the difference between the electricity sales price and the average purchase price, cannot guarantee the return of investment and the sustainable development of the power grid. Based on the current situation of China’s power grid construction and electricity transmission and distribution tariff, this paper proposes that the new investments in the power grid can be divided into technical innovation investments, environmentally friendly investments, service promotion investments and other kinds of investments, according to their functions. Then, four electricity transmission and distribution tariff and power grid investment linkage models are built and example analysis undertaken, respectively, which are the timely linkage model, static linkage model, ladder linkage model, in which the electricity tariff space changes by a fixed absolute value annually and ladder linkage model in which the electricity tariff space changes by a fixed proportion value annually. The results reveal that the ladder linkage model in which the electricity tariff space changes by a fixed absolute value annually can guarantee relatively smooth changes in the electricity tariff, and is suitable for the actual situation of China’s power market. The transmission and distribution electricity tariff and power grid investment linkage models based on sustainable development built in this paper are beneficial for promoting the reforms of the electricity transmission and distribution tariff in China and guiding the establishment of a scientific electricity tariff mechanism. 相似文献

Seven years have passed since the introduction of the liberalisation of the electricity supply industry (ESI) in the UK. Many diverse benefits and applications have been suggested which depend upon efficient bidirectional communications between the utility and its customer base. These applications have included automatic meter reading, distribution automation, load management, remote meter calibration, tokenless prepayment and remote tariff management. However the ongoing development of competition in the ESI in the UK may slow implementation, or even prevent these communications becoming a reality 相似文献
