The Real-time Calculation And Analysis System For The Loss Of The Power Network

The fast development of the electric power industry make the power system more and more complex, and need higher level on the management of the power grid. The calculation of the theoretic loss of the power network is a very important routine of the technical management in the electric power enterprise of our country through which we can find out the feeble parts of the management of loss and adopt some effective methods. On the basis of the comprehensive analysises of the current management of the loss, in the article we brought forward the real-time calculation and analysis theory and technology adapted to the management of the loss. And then a new real-time calculation and analysis system for the loss of the power network was created.In order to set up the theory of the real-time system, in the first, we defined its system of the structure, the system model of the data and the function. The system of structure defined the parts in the system and the function of each part, and offered the network support to the theory. The system model of the data described the characteristics of the data and the sorts and the movement of data based on these characteristics. The system model of function defined the functions and applications related to the real-time calculation and analysis theory . These defined models can describe a complex real-time system, its data structure and its function structure entirely and clearly.Having set up the models of the system, we discussed further some primary problems of the real-time technology, such as the data processing, the calculation of the flow, the calculation of the loss and the effective measures that can decrease the loss etc. The data processing realized the dynamic subsection interpolation to theoriginal data. Through this measure, the data would be more precise and reliable. The calculation of the flow and the loss solved the problems about the real-time calculation of the flow and the loss, showing the characteristics and advantages of the real-time system. In the end, we discussed some effective measures that can decrease the loss, the impact of each method and the compositive impact of some methods. The researches on these problems enriched the real-time system technology, and offered it powerful technical supports.In the end, through the real-time system of calculation and analysis of the loss's operation that we have created, we summarized the powerful practical value of the real-time theory and technology in the management of the loss, and described its prospects of the extensive applications on the other fields.
