摘要
通过实例来说明变频器除了调速功能外,还能节约有功功率和无功功率,特别是节约无功功率对提高电网的功率因数和效率,节约能源,具有积极的意义。
The practical example states that the frequency changer not only has speed-regulating function but also can save active power and reactive power. It is very important that saving reactive power can improve power factor and efficiency of grid and can also save energy.
