The invention relates to a renewable sources intelligent access system of industrial and mineral enterprises, belonging to the technical field of electrical automatic control. The system is mainly characterized in that the system comprises an accumulator used for receiving renewable energy, an inverse power supply, a charging device, a two-way metering device, a double electric energy conversion device and an access cabinet, wherein the double electric energy conversion device preferentially selects the power source provided by natural energy, and when the electricity of renewable energy can not meet the load requirement or the electric system of natural energy is out of order, the double electric energy conversion device automatically selects mains supply. By using the renewable sources intelligent access system, the control and conversion of two way power supply and multifunctional detection between the renewable energy and the mains supply can be realized; multifunction can be set according to the requirements of enterprises; the system has the means of network control, software communication and the like, ensures the rational utilization of renewable energy in industrial and mineral enterprises, saves electrical energy furthest and reduces cost.
Description
technical field [0001] The invention relates to an intelligent access system for renewable energy in industrial and mining enterprises, belonging to the technical field of electric power automatic control. Background technique [0002] The massive development of non-renewable energy has made the earth's resources more and more scarce. With the development of society, the demand for electric energy continues to increase, and the renewable energy system will gradually replace the current energy use mode. At present, the energy access system of industrial and mining enterprises is only suitable for non-renewable energy. If a large amount of renewable energy is developed and put into practical application, especially as the main green energy application, the existing access system of industrial and mining enterprises cannot meet the use requirements. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the energy access system of...
