变电站，改变电压的场所。为了把发电厂发出来的电能输送到较远的地方，必须把电压升高，变为高压电，到用户附近再按需要把电压降低，这种升降电压的工作靠变电站来完成。变电站的主要设备是开关和变压器。按规模大小不同，称为变电所、配电室等。
变电站（Substation）是把一些设备组装起来，用以切断或接通、改变或者调整电压，在电力系统中，变电站是输电和配电的集结点。
变电站主要组成为：馈电线（进线、出线）和母线，隔离开关，接地开关，断路器，电力变压器（主变），电压互感器TV（PT）、电流互感器TA(CT），避雷针。
变电站主要可分为：枢纽变电站、终端变电站；升压变电站、降压变电站；电力系统的变电站、工矿变电站、铁路变电站(27.5kV、50Hz）；1000kV、750kV、500kV、330kV、220kV、110kV、66kV、35kV、10kV、6.3kV等电压等级的变电站；10kV开闭所；箱式变电站。
变电站是电力系统中变换电压、接受和分配电能、控制电力的流向和调整电压的电力设施，它通过其变压器将各级电压的电网联系起来。
变电站起变换电压作用的设备是变压器，除此之外，变电站的设备还有开闭电路的开关设备，汇集电流的母线，计量和控制用互感器、仪表、继电保护装置和防雷保护装置、调度通信装置等，有的变电站还有无功补偿设备。变电站的主要设备和连接方式，按其功能不同而有差异。
变电站在特定的环境中；是将AC—DC—AC转换过程。像海底输电电缆以及远距离的输送中。有些采用高压直流输变电形式。直流输电克服交流输电的容抗损耗。具有节能效应。

Grid in XI ' an historical maximum load to 3.531 million kilowatts, 15.997 billion kWh in electricity sales.
Substations, and conversion sites. In order to transport the electricity to power plants emit more distant places, voltage must be increased, high voltage electricity, near the users if necessary bring the voltage down, elevating substation voltage work to complete. Major equipment are switches and transformers in substations. According to the different sizes, referred to as substations, power distribution rooms and so on.
Transformer substation (Substation) is assembled some of the equipment, to cut off or put through, alter or adjust the voltage, power systems, substation is the staging point for transmission and distribution.
Substation main components: supply lines (line, line) and bus bar, disconnector, earthing switches, circuit breakers, power transformers (transformer), PT TV (PT), TA in current transformer (CT), the lightning rod.
The substation can be divided into: hub, Terminal substation substation; step-up substation, step-down power; power system substations and industrial and mining substations, railway transformer substation (, 27.5kV);, 1000kV, 500kV, 330kV, 220kV, 66kV, 35kV, 10kV, voltage level substation 10kV switch station; box-type substation.
Transformation substation electric power system voltage, acceptance and distribution of electrical energy, control the flow of power and adjust the voltage of electric utilities, through its transformer voltage power grid linking at all levels.
Device is a transformer substations transform voltage, in addition, also opening and closing circuit switching equipment of substation equipment, bringing together current Busbar, metering and control transformers, meters, relay protection and surge protection devices, communication devices, reactive power compensation equipment in substations. Major equipment and substation connections, according to their different functions differ.
Substation in specific environments; AC-DC-AC is the conversion process. Like a submarine transmission cables as well as long distance transportation. Some use high voltage direct current power transmission form. Resistance of DC power transmission capacity to overcome AC transmission loss. With energy-saving effect.
