High Voltage Electrical Power Design

This Program is designed for Electrical Engineers, Engineering Technicians and Technologists who want to gain more knowledge in the domain of power systems and substation design, relay protection and coordination calculation and testing.

The charging of batteries for electric cars requires a significant amount of energy; this, paired with the number of electric cars increasing exponentially, will require the availability of charging options in residential areas.

New substations will be required as the number of electric cars increases.

Green energy usage will increase in residential areas which will create an occasional surplus of energy; the subsequent voltage increase may create problems at the transformer level which will require new types of transformers being employed.

Substation Design and Relay Protection Coordination refers to the design of a Medium Voltage Substation using Easy Power.

The Substation Design needs to accommodate all the new functions for a developing electrical system including the Distributed Generation. Substations may be of various types and different voltage levels:

• High Voltage Substation: required to step up voltage from the Utility Generator to the Transmission Lines.
• Transmission Lines Substations: used for diverting the active and reactive power flow or to compensate for the voltage loss under increase demand.
• Distribution Substation: required to step down the voltage from the transmission lines to the consumer.

Relay Protection Coordination is changing rapidly with the implementation of new technology; in use today are fiber optic current transformers with loss phase protection for power transformers and substations.

The old electro-mechanical relays are being replaced because of obsolescence, i.e. there are no more available spare parts. Opportunities will arise in Relay Protection and Coordination upgrade projects or in the design of new substations with new technological requirements.

The quick change of Electrical Systems requires specific knowledge in the design and calculation of the new type of substations, therefore there are many opportunities in this domain for electrical engineers/technicians/technologists.
