Preamble

A proper design of an electricity distribution system is significant for industrial plants regarding to their safety, reliability, and cost/consequence of power outages. It is necessary to consider the operation safety and the costs/consequences of power outages due to loss of productions and damage of equipment/properties, when making design decisions for either building a new industrial-plant electricity distribution system or refurbishing an existing distribution system. This project is to design a new electricity distribution system for a typical industrial plant. Components (bus bars, feeders, cables, transformers, breakers, disconnects, fuses, etc.) in every circuit/branch of the plant electricity distribution network shall be sized and rated adequately to be able to carry the required industrial loads, withstand typical surges/transients, and interrupt faults. An effective protection system, embedded with coordinated automatic fault-clearing actions, is to be designed and implemented in the distribution network to minimize outages/damages due to faults of various kinds and occurrences.

Objective

The objective of this project is to design a new reliable electricity distribution network for a typical industrial plant, with an effective protection system to be embedded in the network, to offer safe and reliable operations and to minimize power outages and equipment damages due to various fault conditions.

Partial Specifications

Design an electricity distribution network to carry typical industrial loads.
Design a protection system embedded in the network to minimize power outages and equipment damages.
Coordinate protections of major network components including supply lines, transformers, switchgears, fuses, MCC (motor control centers), motors, and other typical industrial loads.
Provide detailed design data such as value, size, rating, length, manufacturer, and model/part# for every component in the power distribution network.

Suggested Approach

Study IEEE Standard 141-1993, “IEEE Recommended Practice for Electric Power Distribution for Industrial Plants”.
Study IEEE Standard 493-2007, “IEEE Recommended Practice for the Design of Reliable Industrial and Commercial Power Systems”.
Study IEEE Standard 399-1997, “IEEE Recommended Practice for Industrial and Commercial Power Systems Analysis”.
Study IEEE Standard 242-2001, “IEEE Recommended Practice for Protection and Coordination of Industrial and Commercial Power System”.

Group Responsibilities

Determine the kind and size of the industrial plant that the distribution system is to be designed to supply electricity to. Define a preliminary configuration of the industrial electricity distribution system to be designed. Divide the preliminary configuration into three (3) sections, of which each section requires equivalent amount of design work and level of design difficulty to solve. Each designer to carry out one (1) section of the whole design. Discuss each section of the preliminary system with the FLC, and obtain the approval from the FLC prior to carrying out the detailed individual design work. During the individual designs and particularly near the end of individual design work, coordinate the designs of all 3 sections and finally produce one complete design of a reliable electricity distribution network for the industrial plant.

Student A Responsibilities

Carry out Section 1 of the whole design, with a prior approval from the FLC. Propose the milestones for Section 1 design work. Obtain the FLC’s approval of the milestone proposal. Provide the detailed design for all Section-1 network components (bus bars, feeders, cables, transformers, breakers, disconnects, fuses, etc.) with detailed data such as value, size, rating, length, manufacturer, model/part#, etc. Provide the protection for all Section-1 network components and their protection coordination. Report in writing the findings of each milestone

Student B Responsibilities

Carry out Section 2 of the whole design, with a prior approval from the FLC. Propose the milestones for Section 2 design work. Obtain the FLC’s approval of the milestone proposal. Provide the detailed design for all Section-2 network components (bus bars, feeders, cables, transformers, breakers, disconnects, fuses, etc.) with detailed data such as value, size, rating, length, manufacturer, model/part#, etc. Provide the protection for all Section-2 network components and their protection coordination. Report in writing the findings of each milestone.

Student C Responsibilities

Carry out Section 3 of the whole design, with a prior approval from the FLC. Propose the milestones for Section 3 design work. Obtain the FLC’s approval of the milestone proposal. Provide the detailed design for all Section-3 network components (bus bars, feeders, cables, transformers, breakers, disconnects, fuses, etc.) with detailed data such as value, size, rating, length, manufacturer, model/part#, etc. Provide the protection for all Section-3 network components and their protection coordination. Report in writing the findings of each milestone.
