Generator Technical Characteristic Testing
- Performance of on-site testing, simulation, and analysis to derive generator facility model parameters, which are essential for reliable power system operation
- Test Cycle (Standards for Maintaining Power System Reliability and Power Quality)
| Div. | Thermal Power | Combined-Cycle Power | Hydropower |
|---|---|---|---|
| Class 1 | 500MVA↑ | 400MVA↑ | 200MVA↑ |
| Class 2 | 500MVA↓ | 400MVA↓ | 200MVA↓ |
-
Test Cycle (Standards for Maintaining Power System Reliability and Power Quality)
- When a generator is newly installed, expanded, or modified
- When modules of the exciter, governor, or power system stabilizer are replaced
- When neither Item 1 nor Item 2 has occurred within the past 10 years
