The invention relates to an electric power quality economic loss and energy-saving benefit evaluation and analysis system establishing method. The method comprises the steps of data demand analysis: establishing an electric power quality economic cost composition framework by analyzing an electric power quality economic cost composition and electric power quality economic data model, function demand analysis: quantitatively evaluating an electric power quality disturbance influence factor, acquiring an evaluation factor for evaluating electric power quality response event uncertainty based ona fuzzy theory, a normalization method and process immunity time, and establishing an electric power quality economic loss statistic model, and system structure analysis: analyzing the following structure functions: an automatic data monitoring function, an electric power quality economic loss and energy-saving benefit evaluation data automatic calculation function, a document uploading function,a portal display and system integration function and an authority management module function. An energy-saving and comprehensive benefit evaluation method arising from electric power quality is improved, and the decision support is provided for a power grid and a user.
Description
technical field [0001] The invention relates to a method for establishing a power quality economic loss and energy-saving benefit evaluation and analysis system. Background technique [0002] For a long time, power quality has been regarded as a technical issue by the attention of power users and grid companies. Power users care about how to obtain high-quality power supply voltage to ensure production efficiency through technical means, while power grid companies care about how to reduce power quality interference from power users to the power grid through strengthening management, and improve the power quality level of the power grid through technical means. In essence, the above-mentioned technical issues concerned by both the power supply and the consumer are driven by the economics of power quality, and the main problem at present is how to analyze the economics caused by power quality, that is: to effectively measure the loss of power quality Calculate and reasonably ...
