The Gujarat Energy Transmission Corporation (Getco) has tied up with IIT-Bombay to develop a dynamic stability analysis (DSA) programme for ensuring grid stability in the State.

The protection systems on transmission lines are the first level of security, which are quite robust. The DSA will form the second level of protection and ensure additional security for network stability, said S K Negi, Managing Director, Getco.

Negi was in Mumbai to address a workshop on grid operation & monitoring, organised by Getco and ABB at IIT-B on Tuesday.

DSA is software-based and equipped with analytical tools to help correlate data received on parameters such as voltage, frequency and phasor angle (the angle of the sine wave) real time, at the State load despatch centres.

Will renewable energy generators feeding the grid, managing the network is an issue, Negi added.

SA Soman, professor at the Department of Electrical Engineering, IIT-B, said DSA would help in the decision-making process of operators at SLDCs such as islanding or shutdown in case of emergencies to avoid blackout situations.

Soman said there was still some way to go for the development of a self-healing network to avoid breakdowns. The main issue in self-healing networks was automation and sufficient safeguards had to be in place to make them operational.
