The invention discloses a regional power grid AVC system evaluation system. The regional power grid AVC system evaluation system comprises a power grid safety acquisition module, a system accuracy acquisition module, an efficiency evaluation acquisition module, a weight determination module, an evaluation module and an output device. The evaluation module is connected with other modules and receives the data acquired by each module; the output device belongs to an LED display; the power grid safety acquisition module is used for acquiring the voltage and the power factor of the power grid; the system accuracy acquisition module is used for acquiring time, strategies and the service condition; the efficiency evaluation acquisition module is used for acquiring the reactive voltage evaluation data and the operation loss data; the weight determination module sets the weight corresponding to each type of data according to the type of the acquired data of each module; and the evaluation module retrieves the corresponding weight from the weight determination module after receiving the data, and utilizes a fuzzy comprehensive evaluation method to calculate the evaluation result. The regional power grid AVC system evaluation system utilizes the fuzzy mathematic theory to evaluate a plurality of evaluation indexes, and the result is clear and the systematicness is high.
Description
technical field [0001] The invention relates to an AVC system application module, in particular to an evaluation system for an AVC system of a regional power grid. Background technique [0002] Voltage is an important operating indicator of the power system. A good voltage level is the guarantee for the safe and stable operation of the power system, and it is of great significance to reduce network losses and improve the economic benefits of the power grid. In recent years, the automatic voltage control system (AVC) has gradually become an important means to increase the system voltage level and improve the system's economic benefits. The AVC system of the regional power grid can help the on-duty staff to analyze abnormalities and deal with faults more intuitively. Correctly and effectively judge the importance level of abnormalities, so that monitors can accurately grasp key abnormalities and take corresponding measures more efficiently. At present, many documents point o...
