S20S3 is an electronic relay system developed by the company ATKINS, and is short for static synchronous series compensator. This device can be used for power system voltage control, phase shifted transmission, power oscillation damping and other power network functions. It consists of a Thyristor-controlled reactor (TCR) using a thyristor switch at its end and a line of Controlled capacitors (CC).

The S20S3 system\'s main function is to control and maintain the system voltages so that the quality of power delivered to the end-user can be ensured. This system can be used to manipulate the local transmission line voltage and current in order to reduce power transmission losses, decrease the excitation loss, and support the power system stability. Moreover, it is also able to damp out system oscillation.

In terms of application, the S20S3 system can be used in a variety of industries, such as coal and nuclear power plants, aluminum smelters, and wind and hydro power plants. It is ideal for controlling system voltage and damping out oscillations that can cause an excess of power to be supplied to the grid during times of high demand. This preventative system helps to reduce power transaction losses and improve the efficiency of the grid.

When considering the working principle of the S20S3 system, it is important to look at the individual components that make up the system. The TCR is an inductor that utilizes the transistor pair to provide a stable alternating current for the system at different voltages. The CC is a series of variable capacitors connected to the line that helps to maintain the voltage stability and prevent voltage surges. Both components work together to reduce current passing through the system and thereby reduce power consumption.

In order to maximize the efficiency of the S20S3 system, the current must be adjusted according to the frequency of the grid. This is done by using the Thyristor-controlled current of the TCR. The voltage is regulated by the CC and the current is regulated by the TCR. Together, they keep the voltage steady and control the current in order to transfer the power efficiently from one point to another. They also help to protect the system from power fluctuations and voltage surges.

The S20S3 system is a powerful tool for controlling system voltage and current efficiently, as well as for damping out oscillations that can occur during times of high demand. This system can be used in many different industries, such as coal and nuclear power plants, aluminum smelters, and wind and hydro power plants. It is important to understand the working principle of the S20S3 system and its components in order to utilize it to its fullest potential.
