Research And Implementation Of Supervision In Electric Power System

As the power system network of our country was transformed on a large scale, the scale of the electric netting developed at full speed, in order to meet security, stability, efficiency of the power network, require it to monitor running situation that software can control the whole electric wire netting to the electric monitoring system synthetically, control a working state of the apparatus, realize " four remote" (telemetering, telesignalling, remote control, remote control), realize report form turn into automatically, and real-time data reveal, historical data inquiry, crash analysis, report form print function, etc.After the electric deployment system develops to have joining of computer technology gradually, the monitoring system was structurized gradually, the electricity in conformity with it appears to control the software. This text is on the basis of studying domestic and international and popular configuration software at present, to the electric deployment system, has mainly designed a power network to monitor the platform, have realized the basic function that the monitoring system needs. In windows2000/NT system, monitors interfaces to design with the configuration software, and realize the dynamic chaining of the data through SQL database.Monitoring the software system has mainly designed several following parts:(1) The electric wire netting mainly wires the picture. Reveal the voltage transformer, circuit breaker, isolate the running situation of the switch and technical data ocularly.(2) Curve system. The curve of data such as the electric current, voltage, power , etc. reveals in the electric wire netting; Shown by real-time curve, historical curve, roll picture ,etc.(3) Warning system. Produce warning information to all kinds of troubles or accidents, administrate the historical record.(4) System of the report form. Divided into real-time report form, daily sheet, annual report. Can connect to the database, and classify the information of the data according to the operator's requirement to reveal.(5) User management. Set up the usufruct of the administrator, operator, customer. The size of the authority is distributed in unison by the administrator.(6) Equipment control. Technical data of voltage transformer of centralized management, switch ,etc.. The picture of this monitoring system is of simple structure, ocular, it is convenient to operate management. Fully meet the requirements for real-time character, dependability of power system, can control the safe operation of the electric wire netting fast, effectively.
