The modern industrial units rely heavily on an efficient flow of electricity for their production and management operations. Complex distribution systems are used for the transmission of heat from the power plant to industries. Are you thinking of building or scale up the electrical system in an industrial plant? If yes,
read on this article as it provides you a step-by-step guide for designing an industrial electrical system.
The primary goal of building an industrial plant electrical system is to have an energy-efficient system, continuity, safety and selection of commercial equipment in compliance with codes. Steps listed below will help in reducing possible system design delays, equipment selection and more. The final equipment cost is determined after the completion of the detailed engineering design process.
The following main steps need to be performed in the design of an industrial electrical system.
Electrical Load Determination
The electrical design engineer receives information on the size and type of electrical energy consumed loads from mechanical and process engineers. It helps to reserve the necessary power for dedicated equipment.
- Determine motors that drive pumps, compressors, air coolers, and more.
- Electrical heaters for heating applications of different products
- Heat tracing to keep liquids and fluids at desired temperature level and protect against freezing
- Essential lighting components
- Socket outlet and HVAC loads
Power Supply
It is necessary to describe the electrical energy demand needs for the loads mentioned above. The general aspects of power points into the industrial plant to the utilization points are determined in this phase.
Generated Power
The electrical energy requirement is generally produced from one or more than one generator without connecting it to a public utility system.
Import Power
In import power configuration, all the energy requirements of the industrial plant are supplied from electric utilities through incoming power lines with sufficient capacity to carry the peak load. The main functionality to consider for electrical system design are reliability, line voltage and the number of feeder connection to the industrial plant.
Combined Generated and Import Power
Generators are operated in parallel along with external utility sources to increase the power flow of electrical loads. Despite the general or partial failure in one of the power sources, generators or utilities continue to supply the electricity demand of industrial plants without shutting down.
Emergency Power Supply
During general or partial electrical failures, uninterruptable power sources – AC or DC or both are supplied to meet the energy demand of critical equipment. Star Plus Energy
