Seminar Overview
In power system networks, substations maintain continuity of supply connecting the power system network from the generation through to the consumer via transmission and distribution networks. High voltage substations include significant plant and equipment such as circuit breakers, transformers, capacitors, reactors, and equipment for protection, control, automation and communications. Substation design involves establishing a reliable and efficient electrical infrastructure for power transformation, distribution, and protection. It is essential that the substation is adequately planned and designed to provide a robust and reliable supply of electrical energy. Common constraints and requirements include compliance to environmental, cultural and community concerns and impacts, which require interaction with network service providers, consumers, and authorities.
This 3-day seminar will cover most of the important aspects of indoor and outdoor high voltage substation planning and design including :
¨ Fundamental substation design philosophy
¨ Design inputs and parameters
¨ Safety and regulatory compliance
¨ Plant and equipment selection
¨ Single line diagrams, general arrangements and layout
¨ Future substation developments
¨ Substation design preparation
– Environmental considerations
– Major plant and equipment
¨ Substation Design
– Primary design
– Secondary design
– Protection schemes
¨ Substation buildings, control/switch rooms
¨ Substation Safety and hazards
¨ Testing and Commissioning
Various practical examples, exercises and experiences will be presented demonstrating certain principles of design.
