Line loss is the loss caused by power supply enterprises in electricity transmission, distribution, management and other aspects of the inherent loss. Line loss rate is an important indicator to measure the power supply enterprise grid construction and operation and maintenance management level. Power supply enterprise operating efficiency, good or bad, to a large extent depends on the control and management of the business-to-line loss rate. At present, the domestic line losses statistical assessment method is "quartering", referring to the power supply enterprises under the jurisdiction of the grid to take the Comprehensive Loss Reduction Management, partial pressure, partition, sub-line and sub-station area, including the line loss management. Quartering is not the calculation method of line loss or line loss rate, actually, it is a management method of line loss rate and analysis by four statistical methods. Quartering integrated, comprehensive assessment of a production, operation and management of power supply enterprise level. Line loss of function of the system is based on the day-to-day operations of the power supply enterprise data and other basic information, in accordance with the line drawn by the actual wiring loss statistical relationship after a certain algorithm to calculate the actual line losses, and then calculated the theoretical line loss compares assessment, analysis and decision-making staff and leadership of the power supply enterprise data.This article system requirements analysis and design using UML (Unified Modeling Language), developed a unified software process guidance, as the whole process using J2EE architecture and introduces the concept of multi-tenant, complete set of line loss management SaaS-based system. Mainly includes the maintenance from basic information, the power to obtain and calculate statistical business processes of the entire line loss of function after the line loss statistics until Report Print.The paper first discusses the current importance of line loss system, and the use of similar systems of power supply enterprises in the province, and then proposed to solve the problem of this topic. Subsequently, after the requirements analysis, architecture design, detailed design, elaboration until the system implementation.This paper studies the following key issues:1. Electricity data access Power line loss calculation of basic data line losses, and if you can not get the data, the statistics will pay double the workload. Due to the power company electricity source data in multiple heterogeneous systems, these systems also may be associated with the line loss management in the different networks, and therefore how fast, accurate access to the power source of data for line loss practicality very substantial the impact.2. Power calculationElectricity significance lies in the calculation of line loss management system so that the unity of the electricity data to prevent excessive deviation of the statistical results of the line loss, the loss of the value of its decision-making based on. Power calculation is a very complex task, you need to take into account a variety of grid wiring. In this paper, using preset rules to solve this problem.3. Quartering line loss and StatisticsThis is the core of the line loss management system, is most concerned about the part of the user. Correct or not of the statistical results and a show of friendship directly related to success or failure of the line loss management system. Flexible and universal relationship set used in this paper to meet the individual needs of the user statistics line loss.4. Build a Multi-tenant applicationsMulti-tenant applications enables customers no longer like the traditional model did spend a lot of investment for hardware, software, personnel, and only need to incur certain costs of leasing services via the Internet will be able to enjoy the hardware, software and maintenance services, the right to software use and escalating; company projects do not like the traditional model requires a lot of time for the layout of the system, the majority can use a simple configuration. This is the most efficient mode of operation of the network applications.Running the system has been implemented in a number of power supply enterprise in the province, to customers reflect running well, and the system is stable, and a significant reduction in business operator handling time, reducing the intensity of the work.
