Description
Mastering Interlocking in BESS Substations:

Substations are the backbone of power transmission and distribution networks, ensuring the safe and reliable flow of electricity. Understanding their fundamental components and interlocking systems is crucial for electrical engineers, protection specialists, and substation designers. This course provides a structured and practical approach to mastering primary equipment, interlocking mechanisms, and the latest advancements in substation automation.

The course begins with a foundational understanding ofprimary substation equipment, covering isolators, earth switches, circuit breakers, current transformers (CTs), voltage transformers (VTs), and surge arrestors. Each component is explored in detail, with a focus on its operational principles, applications, and best practices in design and maintenance. Engineers will gain a clear understanding of how these devices contribute to substation reliability and safety.

Moving forward, the course delves intosingle-line diagrams (SLDs) and elevation reviews, helping engineers interpret and analyze substation layouts effectively. A special emphasis is placed onon-load bus transfer schemes, which ensure a smooth transition of power sources in substations. The distinction betweenprimary and secondary engineeringis also thoroughly discussed, helping professionals understand their interdependencies in substation design and protection.

A major highlight of this course is its in-depth exploration ofinterlocking systems, particularly forBattery Energy Storage Systems (BESS). As the power industry shifts towards renewable energy integration, BESS solutions play a vital role in grid stability. The course covers BESS-specificSLDs, interlock tables, and practical examples of interlockingto enhance understanding of how these systems are implemented in real-world applications.

Additionally, the course introducesCastell key interlocking systems, widely used for mechanical safety interlocking in substations. Participants will learn how these systems prevent unsafe operations and enhance personnel safety. The course also coversBay Control Units (BCUs)and their role in implementingsoft logic-based interlockingstrategies.
