The Generator Protection Relay Application, “AEL-GPRE”, has been designed by Edibon for the training at both the theoretical and practical levels in the field of high power generators with control and protection systems.
This application presents several levels of training to give the user full knowledge and experiences about the operation of advanced protection systems used in large power plants with electrical generators: a specific manual in which are theoretically studied all aspects related to electrical generators such as types of electrical generators, basic principles of generators operation, control and stand-alone generator operation, parallel generator operation with the national grid, types of protections used to protect these machines, sizing and protection relay settings. On the other hand, they are provided a series of modules for putting students’ acquired knowledge into practice.
The AEL-GPRE application includes a series of modules that make it leadership in the market:
- The Generator Protection and Control Relay Unit:
- Turbine Speed Controller:
- Automatic voltage regulator:
- Faults simulation module:
- Network Analyzer Unit with Data Acquisition:
- Three-Phase bank of Commutable Resistors Module:
