Power System Restoration Strategy during Emergency & Blackout

The primary objectives of Power System Planning and Operation are to minimize system outages, Load Interruptions, and Equipment damage under Emergency Conditions. These goals are becoming more difficult to achieve because of the increasing pressures resulting from fast system demand growth and increased system complexity. There are strong influences to reduce operating and maintenance costs and to work equipment harder and longer.

Power System behavior under Emergency Conditions, as well as during restoration processes, depends on its characteristics as related to real and reactive power balance, and the installed control and protective systems. The restoration process is also a function of pre-disturbance conditions, post-disturbance status, and post-disturbance target systems. Therefore, the understanding of the factors involved in power system collapse and in the restoration procedure is crucial to the proper operation of Modern Power Systems.

 

The first focus of the course is on all the major issues associated with system restoration, including those associated with system characteristics and operating conditions. It is argued that restoration planning and training an ongoing activity that involves system operators, planners, protection staff, and trainers. The second focus is on implementing some of the principles gained in a hands-on environment using the EPRI Operator Training Simulator. The students will be asked to carry out several “scenarios” involving restoration from a partial blackout, as well as complete a black start. The principles of top-down versus bottom-up approaches will be practiced and evaluated using a realistic power system model.
