Description
Technical field
The invention belongs to intelligent grid Distribution Automation Technology field, is a kind of line loss actual measurement and localization method based on high-voltage electric energy meter specifically, and the system that realizes this method.
Background technology
Line loss rate is the integrated technology economic index of electric power system, also is a principal economic indicators of power department.The height of line loss rate had both reflected the quality of a power network constructional aspect and management, also reflected the height of a power department technology management level.Analyze the data of line loss accurately, the kind of the classification of line loss, accurate in locating line loss point, bent other loss, distinguish normal loss, unusual loss, or stealing, very important to the energy conservation of electric power system.State Grid Corporation of China to line loss management work pay much attention to, put into effect " State Grid Corporation of China's power network line losses administrative provisions ", spell out and will set about carrying out the power network line losses management from the measure of strengthening management and two aspects of technical measures.Wherein, control measures importance is exactly the line loss INDEX MANAGEMENT.It is thus clear that improve the level of line loss management work, it is crucial formulating a scientific and reasonable line loss index.For grid; Because measuring equipment is complete; Grid equipment parameter and service data ratio are easier to obtain, and the accuracy of data is higher, and theory wire loss calculates and actual line loss statistics is easy to realize; Administrative department is relatively more comprehensive, true to the grasp of high voltage power transmission net wire loss situation, formulates a scientific and reasonable line loss index also than being easier to.Yet; As far as power distribution network, owing to receive the not restriction of congruent multiple factor of measuring equipment, the operational data collection difficulty of its load point or can't accurately collect; This makes power distribution network theory wire loss result of calculation and actual value differ bigger on the one hand, can not accurately add up actual line loss on the other hand.Therefore, making scientific and reasonable power distribution network line loss index at present also has difficulties.In addition, the direct user oriented of power distribution network, the tax evasion electrical phenomena is more outstanding, is the main source that causes the management line loss.In recent years, because many-sided factors such as construction and management, city and rural power distribution net wire loss level are still higher, and economize on electricity is fallen to decrease and had a high potential.
