Reactive Power Compensation Services and Study is the regulation and control of reactive power to improve the performance of alternating current or AC.
Concerns about load and voltage frequently supported link to reactive power adjustment.
The goal of load support is to improve voltage control, balance real power consumption from the alternating current supply, and reduce current harmonic components caused by large, fluctuating nonlinear industrial loads.
Voltage supported typically requires reducing voltage fluctuation at transmission line terminations.
Reactive power adjustment in message systems improves ac system stability by increasing the maximum active power that can be provided.
Because reactive power has a larger capacity required, it is best to use it only when necessary. The distribution system’s equipment also aligns with the reactive power generated by a power plant. Electric power networks require reactive power to function. Rotation in rotating machinery cannot begin without reactive power, and active power not transfer through transmission lines without reactive power. The ability to modify or compensate for reactive power has several advantages. Positive and/or negative VArs add or inject into the power system during the reactive power compensation process to achieve voltage regulation. Alternating current (AC) us to generate, transfer, distribute, and use electrical energy (with a few exceptions) (AC). However, there are some drawbacks. One of these requirements is the provision of reactive power in addition to active power. You have the option of being a leader or a follower.
Reactive Power Compensation Services Provide in a Variety of Ways:
Reactive power compensation services are provided in one of three ways. They are as follows:
Shunt compensation: On transmission lines, reactive power is balanced by using shunt-connected capacitors to maintain voltage levels, While shunt-connected reactors us to reduce line over voltages by consuming reactive power. A shunt compensator always connects in the center of the transmission line and parallel with it. a current or voltage source, or both. An ideal shunt compensator provides reactive power to the system.
Series compensation: To reduce voltage loss over long distances and the Ferranti effect, a series compensator line is used to reduce the reactive impedance of the transmission. It link to the transmission line in series. A series compensator add at any point along the line. Capacitive and inductive operations are the two types of operations. The magnitudes and phase angles of the voltages on the two buses are thought to be similar.
Static VAR compensators: SVCs are electrical devices that provide reactive power in transmission networks. Static compensators, as the name implies, show no movement in the system components. If the reactive load on the power system is capacitive, the SVC will use reactors (typically thyristor-controlled reactors) to absorb system v必利勁
ariables, lowering system voltage (leading). When the reactive load is inductive (lagging), the capacitor banks are automatically activated, resulting in a higher system voltage.
Reactive Power Compensation Services Come in a Variety of Forms:
Capacitors are the most common and widely used pF correction solution in Reactive Power Compensation Studies around the world, and the following voltage control types use depending on the capacitor’s position.
Distributed power factor correction: In this type of power factor correction, capacitor banks connect to the terminal of the load that requires reactive power. This installation method is both cost-effective and simple. The overcurrent protection device use by both the capacitor bank and the load. result, it connect and unplug at the same time. This type of power factor adjustment recommend for large loads that will connect to the system for extend period of time. Both induction motors and fluorescent lighting necessitate distributed power factor correction.
Group power factor correction: For loads that perform similarly, group power factor correction is commonly used. A common capacitor bank is provided to improve the power factor. If you have three similar induction motors used for the same purpose, you can use a shared capacitor bank to modify the power factor. This method cost-effective, but it should only use for light loads.
Combined power factor correction: This is a hybrid of two methods, as the name implies: distributed power factor correction and centralized power factor correction. This method employs distributed power factor adjustment for large loads that run continuously. To improve the power factor of small equipment, a centralized power factor correction method use.
Automatic power factor correction: The majority of systems do not constantly absorb reactive power due to the equipment’s obvious working cycle. Automatic power factor correction systems install in these facilities. As a result, different capacitor banks activate and deactivate according to need. power factor control panels Automatic, called as APFC panels, which widely us.
