The Business Data Flow Analysis And The Database Design For The Technical Supervision Platform System

Power system consists of power generation, transmission, transformation, distribution and consumption of the five sectors constituted the core of the transformer substation equipment, its operational status is directly related to the security of the power system, but also an important consideration factor in the power system reliability indices. The reliability is an important indicator of a transformer is the dielectric loss. To ensure the safe operation of the power system, we must strengthen the monitoring of substation main transformer insulation, insulating dielectric loss measurement is essential preventive experimental test project. By measuring the dielectric loss may reflect a series of defects in the insulation of electrical equipment, such as insulation damp, dirty oil or impregnated material deterioration or degradation of insulation in the air-gap discharge occurred. Therefore, the insulation dielectric loss measurement is essential preventive experimental test project.In a substation, capacitive devices accounted for 40 percent to 50 percent of the total number of substation equipment. The most important of these devices is the main transformer casing, the device is the easiest of all equipment accidents devices, thus the need to invest in preventive tests a lot of work, its relationship to the status of the state ’s power grid, if equipment failure, power will not bring economic losses, serious disaster might occur, failure to pay a huge price for the electricity sector. To ensure the reliability of the system, requires a lot of manpower and material resources and workload. Thus through the transformer bushing monitoring, not only to ensure the safety of the power grid equipment can obtain economic benefits.Through the construction of the system, real-time monitoring of substation main transformer casing equipment operating status, reduce unnecessary maintenance outage time, save manpower and maintenance expenses, reduce costs for electricity operators to win more precious time, greater economic benefits. Through online monitoring technology, according to the data acquisition cycle to achieve continuous acquisition device status, and data analysis methods based on dielectric loss data for scientific analysis, timely diagnosis, prediction analysis of the system based on the parameters to achieve early detection of problems early warning, thereby improving device reliability. At the same time the system can be achieved with the scheduling system interface, remote monitoring of equipment status, to achieve the defective equipment or faulty equipment may have chosen an early overhaul and reduce losses caused numerous power outages. Provide technical support for remote monitoring via unmanned substation.The system was developed using C language based on the integration of C #, data, electronic technology a number of technologies designed to achieve dielectric loss line transformer bushing monitoring system improves the automation through the dielectric loss monitoring, reducing the complexity of the work.
