电力 Electric power

(重定向自Electricity system)
电力透过高压电线输送到不同地区。上图是新西兰400kV电网。
被动组件 (负载) P>0
主动组件 (电源) P<0

电力是指发电机所产生的电能。电功率的国际单位为瓦特。在交流电,视在功率包括实功及虚功。发电机必须同时提供实功及虚功,电力系统才可正常运作。视在功率的单位是伏安(VA),电力公司使用的电容及变压器通常以kVA或MVA作为额定值的单位。

当电流通过一个电路时,它能够转换能量成机械能,或是发热。运用电功率的电器设备的种类很多种,例如发热(电热器)、光(灯泡)、动能(电动机)、声音(扬声器)、或化学变化(电镀)。电功率可以经由发电机产生,或化学反应产生(电池),或是由太阳能(太阳能电池),或是转化为化学能保存于蓄电池。

Power triangle: The components of AC power

Electric power is the rate at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt, one joule per second.

Electric power is usually produced by electric generators, but can also be supplied by sources such as electric batteries. It is usually supplied to businesses and homes by the electric power industry through an electric power grid. Electric power is usually sold by the kilowatt hour (3.6 MJ) which is the product of power in kilowatts multiplied by running time in hours. Electric utilities measure power using an electricity meter, which keeps a running total of the electric energy delivered to a customer.
