Preamble

Electrical power utility companies have traditionally used discrete electronic and electro-mechanical devices for power system monitoring, protection, supervisory control, and metering. Each device independently acquires and processes the power system data from transformers, circuit breakers, tap changers, etc. required to perform its assigned function. This approach acquires the signals through hard-wires and is costly. Modern microcomputer, digital signal processor, analog-to-digital converter, and wireless communication technologies provide an opportunity to acquire and process electrical power system information faster and efficient way remotely.

Objective

-To design, develop and test an integrated (simulated) system for power utility substation monitoring, protection and control. -The typical functionalities available in a substation, as specified below, are to be integrated in one system with focus given to wireless mobile technologies to efficiently and effectively communicate with remote devices. - To simulate and validate the workings of the monitor through the combination of software simulation and embedded implementation.

Partial Specifications

The substation functions to be implemented via simulation are: (a) data acquisition, (b) real-time monitoring via wireless technologies, (c) power system protection, (d) supervisory control, (e) digital fault recording, (f) sequence of events
recording and (g) power quality analysis

Suggested Approach

Study power system protection, control, and monitoring.
-Research on technology for integration of substation protection, control, and monitoring operations.
- Research on technology for wireless device communication with attention given to radio channels, energy-efficient yet reliable communication. Decide on the wireless system to be used.
- Design a data acquisition/monitoring subsystem and develop software for the data acquisition subsystem.
-Design substation protection and control mechanisms and develop software for substation protection and communication and control of subsystems.
-Integrate data acquisition, protection, and control subsystems into one system.
-Test the integrated system for typical/extreme utility conditions which will be done through simulation and some implementation.

Group Responsibilities

It will be done by a group of three students. It is expected that all three are involved in all aspects of the project though one may work exclusively on any project aspect. All have to work on the design decisions to be aware of and be responsible of the consequences of the choices.

Study power systems, interconnection topology, remote communication and control.
Design/develop the technical specifications required for the system prototype.
Implement and test of the entire system with the above objectives. Follow the project management plan carefully and thoroughly.
Responsible for the demo and project report.

Student A Responsibilities

Course Co-requisites

To ALL EDP Students

Due to COVID-19 pandemic, in the event University is not open for in-class/in-lab activities during the Winter term, your EDP topic specifications, requirements, implementations, and assessment methods will be adjusted by your FLCs at their discretion.
