Embodiment Construction
[0019] see figure 1 , A power quality optimization method, which detects the power of the power consumption system in real time through the power detection device, transmits the power parameters to the power quality optimization controller through the industrial local area network, and makes control decisions through the power quality optimization controller, and then passes The industrial local area network realizes that the power quality optimization controller controls the power consumption controller, and the power consumption controller optimizes the power consumption control of the corresponding power consumption system. The power detection device, power quality optimization controller, and power consumption controller all have Profibus-DP and Modbus fieldbus functions, and communicate with each other through an industrial local area network. There are several power-consuming systems, which can be power-consuming equipment, such as motors, electric furnaces, and heaters; i...

The invention relates to an electric energy quality optimization method. According to the method, the electric quantity of an electricity consumption system is detected in real time through an electric quantity detection device; an electric quantity parameter is transmitted to an electric energy quality optimization controller through the industrial local area network; a control decision is made through the electric energy quality optimization controller; then the control of the electric energy quality optimization controller on an electricity consumption controller is realized through the industrial local area network; the electricity consumption controller carries out electricity consumption optimization control on the corresponding electricity consumption system. Compared with the prior art, the electric energy quality optimization method has the benefits that the state of an electricity consumption network can be monitored in real time, so that the purpose of reasonable electricity consumption is achieved, the harmonic wave can be inhibited and the effect of optimizing the quality of a power grid is achieved.
Description
Technical field [0001] The invention relates to an electric energy optimization system. Background technique [0002] As power electronic devices are increasingly widely used, grid loads are becoming increasingly complex. The non-linear, impact and unbalanced power consumption characteristics of the grid load have made the harmonic pollution in the grid increasingly serious. At the same time, it has also brought additional reactive power to the grid, and the power factor has dropped seriously. As a result, the use of electrical equipment and line losses increase, the voltage fluctuates sharply, and the quality of power supply is seriously reduced. Harmonic losses may also affect the normal operation of the equipment, causing vibration, heat, noise, automatic device malfunction, and interference to the communication system. [0003] There are many methods to improve power quality, such as fixed capacitor banks, automatic power factor controllers, etc., but these solutions have good...
