变电站控制室由于存在大量二次设备,发热量大,全年制冷需求时间长,一般采用分体空调器供冷,空调系统用电占变电站自用电比例较高,减少空调系统电耗是降低变电站自用电的关键。为了降低空调系统能耗,对变电站低压设备控制室进行了新风自然冷源改造。选择过渡季节中空调器关闭而新风冷源开启的一天作为系统电耗测试日,实测出新风自然冷源耗电量,模拟计算出空调器耗电量,通过比较得出系统改造的节能量。
Substation control room due to the existence of a large number of secondary equipment, heat, cooling demand for a long time throughout the year, the general use of split air conditioners, air-conditioning system occupies a higher proportion of electricity for substation to reduce air-conditioning system power consumption is reduced Substation self-consumption of the key. In order to reduce the energy consumption of air-conditioning system, the control room of low voltage equipment substation natural air source transformation of fresh air. Select the transition season, the air conditioner is turned off and the fresh air source is turned on the day as the system power consumption test day, measured the natural source of fresh air power consumption, air-conditioning to simulate the electricity consumption by comparing the energy savings derived from the system transformation .
