Industrial Plant Design/System Planning

System Planning

An industrial plant is only as good as its electric distribution system. For this reason, careful system planning for an industrial power system is very important. This wiki outlines the procedures of system planning and presents a guide which will make the details of Electric Power Distribution Design for Industrial Plant more understandable.

A standard electric distribution system is not adaptable to all industrial plants because no two plants have identical requirements. Methods must be used to analyze the specific requirements of the industrial plant qualitatively and quantitatively, and design the system which will most adequately meet the electrical requirements of the particular plant, with consideration given to both present and future operating conditions.

Basic Design Consideration

Any approach to the problems must include several basic considerations which will affect the overall design. These are

Safety

Safety takes two forms; safety to personnel and safety to property. The safety of personnel involves no compromise; only the safest system can be considered.

Safety to property may involve some compromise where safety to personnel is not jeopardized.

Reliability

The continuity of service required is dependent on the type of manufacturing or process operation of the plant. Some plants can easily tolerate momentary outages while others require a very high degree of service continuity. In view of this, the system should designed to isolate faults with a minimum disturbance to the system and should have features to give the maximum dependability consistent with the plant requirements.

First Cost

While the first cost is important, it is often minimized if the system is reliable and its operation is satisfactory. It should not be the determining factor in the design of the plant since distribution cost represents only 2 to 10 percent of the plant investment.
