What is a static variety compensator?
The static VAR (SVC) compensator is an electrical device that is part of the flexible power transmission system (AC). The term "static" is used to indicate that there are no moving parts for SVC. In order to understand the rest of the term, what it is and how it works, it is first necessary to understand reactive power, VAR and high -level transmission network. In the case of alternating current circuits, energy can reverse the direction that flows from time to time. When calculating throughout the wave of alternating current cycle, real power is an average net energy transfer in one or the other direction. The net performance that returns to the source during each complete cycle is known as reactive performance. The VAR static compensator is designed to quickly return the reactive power to the source. It is a Unmi for reactive power in the AC electrical system. Vars describe the level of energy that flows into reactive load.
EL Transfer SystemHigh voltage -out of power is shifting energy from power plants to the substations. One system consists of a series of transmission lines that are connected. In the United States, they are usually called "Power Grids". Eastern connection, Western connection and grid of the Council for Electrical Reliability Reliability (ERCOT) are three systems that make up the backbone of energy transmission in the US. In the UK, the transmission system is simply referred to as "National Grid".
In the electrical power transmission system, the static compensator VAR helps to regulate the voltage and stabilize the grid. SVC responds to the type of reactive load that the system carries. If the load is capacitive or leads, SVC uses a thyristor -controlled reactor or other similar type of reactor to absorb VAR and reduce the total system voltage. When the reactive attachment is inductive or lagging, SVC turns on capacitor banks to increase the system's voltage. These changes occur automatically and help the system run at an optimal level.
There are several advantages of static compensator VAR. First of all, SVC is fast. It can provide almost immediate adjustment of the voltage of the power system. SVCs are also usually cheaper, more reliable and capable of mastering higher energy capacity than other options that could be used to manage the system voltage.
