Power Systems Engineering

About the Division

The PG Programme in Power System Engineering in the Department of Electrical and Electronics Engineering was started in the year 1963 with an intake of 10 students which is currently 30 students. This division has been manned right from its inception by a strong faculty well qualified in various facets of power system engineering. Significant work has been done in the area of power system engineering through research work and industry-institute interaction.

Major areas of Research

Currently, the research work is going on in the areas of Power System Stability, Operation, and control, FACTS controllers, power quality, De-regulation, Grid-connected Wind Energy Conversion Systems and Application of Artificial Intelligence Techniques to Power System Problems.

Infrastructure Facilities

The Division has three laboratories. The Simulation Laboratory with the UNIX operating system is meant for the Under Graduate students. The Advanced Simulation Laboratory is equipped with the application software packages such as EUROSTAG, ETAP, PSCAD/EMTDC and Electromagnetic transient programme to educate and provide advanced training in the analysis, design, and operation of Modern Interconnected Power Systems at postgraduate level. The Project Laboratory extends facilities for carrying out research and consultancy works.

The available facilities are effectively used by the Research Scholars. 17 Ph. Ds have been produced and 20 are ongoing. All the research works are reported in International Conferences and Journals. The candidates pursue research with financial assistantship under QIP, UGC and Dr.Kannoth Sukumarn Fellowships.

Application Software Development

Over the past two decades, research and consultancy activities have been carried out by the faculty of the division. As a part of these activities, a number of software packages were developed for power system studies. These software packages were supplied to TNEB for their use in operational and planning studies. These software packages are also being used by undergraduate and postgraduate students and research scholars for training in regular course work as well as for research works.

1 Software for load flow analysis using fast decoupled load flow method with Sparsity technique 500 buses
800 lines
50 generators
250 transformers
250 capacitors
2 Software for short circuit analysis using Z bus matrix
3 Software for transient stability analysis of multi-machine power systems using alternating solution approach with IEEE models for controllers
4 Software for VAR planning through optimal siting & sizing of static capacitor - minimises total shunt capacitor requirements with generator voltages, taps of OLTC and VAR sources as control, using successive linear programming technique.
5 Software for optimal reactive load flow for transmission loss minimization - minimizes total transmission losses with generator voltage, taps of OLTC and VAR sources as control using successive linear programming technique.
6 Software for interactive load flow analysis - interactive features for contingency simulation and change case power flow analysis - uses sensitivity information to induce convergence in planning load flow.
