Customer ServiceThus, the power factor correction produces economic savings in capital expenditures and fuel expenses through a release of kilovoltamperage capacity and reduction of power losses in all the apparatus between the point of installation of the capacitors and the power plant source, including distribution lines, substation transformers, and transmission lines.
Customer ServiceIn order to understand the usage of different types of capacitors in transmission lines we must first look in different way first the effect of power factor on the power system. Because the subject is related to the power factor correction.
This is the most common method of connection. . The capacitor is connected in parallel to the unit. The voltage rating of the capacitor is usually the same as or a little higher than the system voltage. There are other methods as well that are very useful in order to improve the power factor of transmission lines.
There is the possibility of spurious operation of series capacitor protection due to certain external faults. If the series capacitor protection results in a single phase by-pass/re-insertion, it can be problematic for the transmission line protection on the series compensated line.
As transfer increases across a transmission line, reactive losses caused by the inductive nature or transmission lines are partially offset by the increase in reactive power generated by the capacitor. Consider Figure 2-4, the reactive power balance for a 500 kV line of 300 miles in length.
Series capacitors also help in balancing the voltage drop of two parallel lines. When series compensation is used, there are chances of sustained overvoltage to the ground at the series capacitor terminals. This overvoltage can be the power limiting criterion at high degree of compensation.
Series compensation provides for higher steady-state power flows in the power system and the increase in load current can impact the sensitivity setting of protective relays. Automatic reclosing strategies may be used in conjunction with series compensated transmission lines.
