What is the difference between substation and substation?

Change the voltage of the place. In order to transmit the electric energy from the power plant to a far place, the voltage must be increased to high voltage, and then the voltage should be reduced as needed near the user. This kind of voltage lifting work is completed by the substation. The main equipment of the substation is switches and transformers. According to the size of different, small called substation. The substation is larger than the substation. Substation: generally a step-down substation with a voltage level below 110KV; substation: including "step-up and step-down" substations with various voltage levels. Substation is a power system in the transformation of voltage, accept and distribute electrical energy, control the flow and adjustment of power.

Classification of Substation

(1) Outdoor substation. In addition to the control and DC power supply equipment in the outdoor substation, the primary equipment such as transformers, circuit breakers and blocking barriers are all installed outdoors. This kind of substation construction area is small, the construction cost is low, and the substation with higher voltage is generally selected for outdoor settlement. (2) Indoor substation. The primary equipment of the indoor substation is placed indoors, reducing the total land occupation, but the construction cost is higher, suitable for urban residents full area, or located in the coast, salt lake, chemical plant and other areas with high air pollution level. 3) Underground substation. In the personnel and industrial high concentration of large

The Difference Between Integrated Substation Automation System and Digital Substation

Regular substation is generally a common electromagnetic, capacitive transformer, secondary circuit cable substation; Integrated Substation is an additional integrated automation system on the regular substation, including data transmission, etc., in fact, the difference is not all; Digital substation uses photoelectric transformer, and the secondary circuit uses optical cable.

Substation classification

1. According to the voltage level can be divided into ultra-high voltage, high voltage, medium voltage substation and low voltage substation. The voltage below 1kV is called low voltage; the voltage of 1 ~ 10kV is called medium voltage; the voltage higher than 10kV and lower than 330kV is called high voltage; the voltage above 330kV is called ultra high voltage. 2. According to the difference of power supply object, it can be divided into urban substation, industrial substation and agricultural substation. 3. According to its low position and function in the power system, it can be divided into hub substation, intermediate substation, regional (local) substation, enterprise substation and end (user) substation.
