Policies and ethics Thyristor switched and controlled series capacitor systems were developed in the late 1980s to enable increased load carrying capacity of existing high voltage transmission lines. Thyristor controlled series capacitors (TCSC) would insert a variable series impedance...
It provides information concerning the following: Use this manual if you are responsible for designing, installing, programming, or troubleshooting the Capacitor Bank Controller system. You should have a basic understanding of electrical circuitry and familiarity with relay logic. If you do not, obtain the proper training before using this product.
Reactive power control can be accomplished by means of shunt compensation using capacitor banks/FACTS controllers or by means of series compensation by inserting capacitor in series with the line. For long overhead lines, series capacitors inserted into the overhead line is normally the preferred alternative.
A capacitor bank works by providing or absorbing reactive power to or from the system, depending on its connection mode and location. There are two main types of capacitor banks: shunt capacitor banks and series capacitor banks.
It helps you to shape up your technical skills in your everyday life as an electrical engineer. The purpose of a capacitor bank’s protective control is to remove the bank from service before any units or any of the elements that make up a capacitor unit are exposed to more than 110% of their voltage rating.
The TCSC was equipped with MOV surge arresters as the main protection against series capacitor overvoltages. The TCSC was designed to withstand short circuit current within certain limits. In the event of a short circuit, the MOV arrester starts conducting to protect the series capacitor against overvoltages.
