Electric power has evolved from a simple need to a major necessity. Everyday we rely more and more on electricity to do just about everything. When the lights go out, its not just a major inconvenience, but a catastrophe in some cases. A major focus for power distribution utilities is to deliver reliable power to its customers safely and at the lowest possible cost.
Newer state-of-the-art, digital devices are making it possible to achieve near perfect power reliability while offering more monitoring and control functionality of electric grids. Smarter grids are evolving with improved and faster automation systems, working in harmony with: IEDs, SCADA, FLISR, AMI, AMR, DMS, EMS, OMS, etc.
Protection and Controls (P&C) engineering and design is extremely important in power grid protection and coordination especially with the use of intelligent electronic devices (IEDs). Proper P&C designs and coordination with protective relaying and IEDs is an essential part of electrical power engineering for protecting large expensive power equipment such as: generators, transformers, transmission lines (TLs), power circuit breakers, electrical bus, etc.
Many wonder exactly how the electric power grid works from generation to transmission to distribution and to the end users. There is more to electricity than simply turning on a light switch. Electric power has given us many conveniences and has improved our quality of life forever more, sometimes more than we can imagine. This provides a basic explanation of the electric power grid.
