This course will discuss the need for standby/emergency power generation in industries and the details of engine-based power stations. Achieving large standby capacities would call for multiple generating sets to be operated in parallel and at times synchronized with an external power source.

OPERATION AND MAINTENANCE OF DIESEL POWER-GENERATING PLANTS

OPERATION AND MAINTENANCE OF DIESEL POWER-GENERATING PLANTS

Why this Course 

This course will discuss the need for standby/emergency power generation in industries and the details of engine-based power stations. Achieving large standby capacities would call for multiple generating sets to be operated in parallel and at times synchronized with an external power source. The factors to be considered to achieve proper load sharing and also to safeguard against power grid abnormalities are discussed. A brief description of the engine-based uninterrupted power source is also included.
