Business Intelligence Building Industry
Intelligent environmental protection building refers to the use of wind power generation system, photovoltaic power generation system, photoelectric curtain wall system, car charging station system, healthy new wind system, daylight lighting system, shading and heat insulation window technology, building intelligent system and other 8 energy-saving measures of new energy-saving building.
Chemical industry and new energy industry
1), the load type of the above industry is mainly power electronic rectifier power supply and variable frequency speed control device will produce 5 times, 7 times, 9 times, 11 times, 13 times and other harmonics, with the popularity of 12 pulse and 24 pulse rectifier, low harmonics gradually reduced, 23 times, 25 times harmonic current gradually increased;
The harmonic sources of urban subway traffic can be divided into two major electrical equipment: 1), high-order harmonics generated by high-voltage 35KV side traction rectifier inverter device, the dominant harmonics are 11, 13, 23 25 times;
Iron and steel metallurgical industry
1), high-voltage 35KV side traction rectifier inverter device generated high-order harmonics, the dominant harmonics are 11, 13, 23 25 times; 2), low-voltage side natural power factor is low, at night load work reactive power harmonic wave motion is larger;
