Power systems are complex systems consisting of large number of generating units and interconnected network of transmission lines. The voltage stability is an issue of prime importance in this complex power system network since the demand for electric power is increasing drastically. The control of reactive power in the transmission lines will enhance the voltage stability of the power system network...
The power system faults do occur in power system network and are more frequent in transmission and distribution systems. The behaviour of power system faults changes in the presence of FACTS devices. Accurate detection of these faults is essentially required for providing effective power system protection and relaying system. The relays must operate as fast and accurate as possible to switch off the...
The placement of shunt capacitor banks at optimal locations in the distribution network and their sizing can effectively reduce the losses in the utility network. It also helps in the maximum active power flow through the existing distribution lines which. This also increases the power transfer capacity of feeders and improves the voltage profile of the feeders which leads to reduced investment of...
Transmission line protective relaying is an important aspect of a reliable power system operation. The issue has become critical due to wide spread grid integration of distributed energy sources.
