Static synchronous compensator (STATCOM), a shunt type flexible AC transmission system device, is used to control the voltage at different locations within a power system by absorbing/injecting reactive power. The dynamic control action associated with the operation of STATCOM in both capacitive and inductive modes is the reason for varying system condition and failure of different relaying schemes...
Erroneous measurement of voltage and current signals during power swing causes failure of the protection system. Therefore, fault detection and direction estimation are challenging issues in the power system protection area. In this paper, an integrated directional algorithm is proposed to estimate the direction of unsymmetrical and symmetrical faults during power swing. Scheme 1 is based on the cumulative...
The increasing energy demand of the consumers necessitates the incorporation of generation in distribution level. However, the increasing penetration of distributed generators (DGs) leads to complexity in designing the power system protection schemes. Islanding detection is one of such problem faced in the distributed generation system. In recent years, many techniques are proposed for islanding detection...
The paper concentrates on mode of operation of Thyristor Controlled Series Compensation (TCSC) present in a line using positive sequence based techniques. The positive sequence based technique is taken into consideration as it is present in both balanced and unbalanced fault conditions. Distance protection issues related to degree of compensation, high resistance fault and other fault conditions are...
