1Plant from Design to Commissioning

1.1 Planning

The electrical power distribution systems have to be designed to fit the plant electrical requirements. The power systems must be well planned, considering the technological process, cost, reliability, maintenance, control, operating flexibility, and future growth. Furthermore, the undertaking must take into account the safety of people and equipment, continuity of power supply, installation, and operating costs.

Electrical engineers' responsibility is to prepare design criteria and single‐line diagrams, power system studies, calculate fault currents, locate load centers within the plant, estimate load diversity, select the grounding system, define the routes of overhead lines, prepare plant layouts, and develop the electrical protection ...
