Modern Electrical Power Substation Fundamentals
Note: This is a recorded video presentation and does not qualify as an interactive course nor a live webinar.
This online engineering PDH video presentation will present a basic overview of modern electrical substations, emphasizing their important role in reliable and effective operation of power systems, describing all major, auxiliary, and control equipment, listing typical engineering issues associated with substation design and engineering and providing recommendations for addressing those issues.
This course begins with a brief review of electrical power concepts in the DC, Single Phase AC, Three Phase AC, Per-Unit System in an easy to follow manner. The course then segues into the discussion about main goals that every utility company has, followed by description of a typical power system structure, justification for voltage transformation and mission of substations. Next, all main components of substations including their mission, components, types and arrangement are covered. This course also provides an overview of reliability analysis theory, main equations to calculate probability of failure for both a single element and different kinds of their connection into the system. A basic overview of relay protection philosophy and main components of relay systems is provided, followed by description of most popular types of protection schemes, including their principles of operation, advantages and disadvantages. Next, an overview of reliability analysis theory is provided including main equations to calculate probability of failure for both a single element and different kinds of their connection into the system. This course also covers, briefly, the insulation coordination topic, as well as substation safety and fire protection issues. Explanation of BIL (Basic Insulation Level) and its effect on substation design are provided. A brief introduction to safety and fire protection standards is provided. Then, an example is presented to show how to choose 138 kV circuit breaker for a specific power system.
This 7 PDH video presentation is intended primarily for electrical and civil engineers and designers, construction professionals as well as utility company management and field personnel looking to expand their knowledge and experience in modern electrical substations.
