General Description

The Switching in Transmission and Distribution Substations Application, ,AEL-SST-01,, has been designed to study the most common operations carried out in these substations, such as, transference of the electrical service from the first busbar to the second busbar without interruptions of electrical supply, distribution through two lines in parallel, switching on/off of loads, commanding logic switch-disconnector, etc.

To demonstrate these basic principles of working, this application includes two types of busbar modules:

• Double busbar typology. These modules consist of two three-phase sets of busbars with input/output terminals to interconnect with other similar modules (feeders). Each double busbar module has two disconnectors connected each to each busbar and one circuit breaker. Through the circuit breaker, loads, generators, electrical lines, etc. will be supplied. To control the opening / closing orders of disconnectors and circuit breakers, these modules have push-buttons (local control mode) and digital signals inputs (remote control mode).

• Coupling busbar module, it consists of one coupling three-phase circuit breaker between the busbars and two three-phase disconnectors, which allows coupling the two busbars.

In addition, this application includes a network analyzer to measure voltages of different points, currents, power flows of the different feeders, etc. or a three-phase switch to interrupt the current manually or remotely.

The AEL-SST-01 has been designed to be combined with the rest of AEL-TI applications in order to form a system in which the user can learn concepts about generation, transmission, distribution and power consumption.

This application can work remotely through SCADA software AEL-TI-07/CCSOF included in the base unit AEL-TI-07. Transmission Application with Synchronous Generator.
