The invention relates to an electric energy quality optimization method based on fieldbuses, which is characterized in that an electric quantity detection device detects the electric quantity of an electric system; the electric quantity parameters are transported to an electric energy quality optimization controller through an industrial local area network; the electric energy quality optimization controller makes a control decision and controls an electric controller through the industrial local area network; and the electric controller carries out electric optimization control on the corresponding electric system. Compared with the prior art, the method has the following benefits: by the method, the state of the electric network can be monitored in real time to achieve the aim of reasonable electricity usage, reactive power of the electricity grid can be compensated in real time and harmonic waves can be suppressed to achieve the optimization effect on the quality of the electricitygrid.
Description
technical field [0001] The invention relates to an electric energy optimization system. Background technique [0002] Electric energy is the basis of modern economic development and an important social constraint factor, which is related to economic security and national security. Most of the current electric energy comes from non-renewable fuels. Based on this factor, electric energy is also related to issues such as energy saving, emission reduction, and environmental protection. [0003] Therefore, improving the quality of electric energy and saving electric energy is a problem that the society pays close attention to at present. [0004] With the increasingly widespread application of power electronic devices, the grid load is becoming more and more complex. The nonlinear, impulsive and unbalanced power consumption characteristics of the grid load make the harmonic pollution in the grid increasingly serious. At the same time, it also brings an additional reactive power...
