And Control

With increase in deregulations and renewable sources of generation, the power system network is leading towards more geographical spread and interconnectedness. This causes significant challenges requiring on-line monitoring and control. It also provides a path for disturbances to propagate causing cascading failure, even blackouts. Wide area detection of potential island formation and controlled separation is considered as an effective tool against a blackout under severe disturbances. In the present work one line remaining algorithm has been utilized for implementation of controlled islanding in a section of Indian power grid.

Power System Monitoring

Phasor Measurement Units (PMUs) are becoming prominent in enhancing the situational awareness in wide area power system monitoring, thereby playing a vital role in its protection and control. This paper focuses on enhancing the situational awareness of transmission line using National Instruments (NI) based PMU. The data measured by the virtual PMU is used for fault detection and fault classification. The detection and the classification in the LabVIEW platform are performed using the Fourier Transform and support vector machines (SVMs) respectively. The proposed methodology has been applied on a laboratory set up consisting of transmission line, three phase load and an NI based PMU. The enhanced situational awareness in the detection and classification of transmission line faults helps in restoration of the transmission line as quickly as possible and trigger wide area control actions to maintain power system stability against the disturbances created by a fault.
