Automatic separation of TPP auxiliaries in the event of an emergency frequency or voltage transient in the grid
- 40 Downloads
The existing methods of isolating the TPP auxiliaries in the event of an emergency frequency and/or voltage transient in the grid are discussed. Requirements to the actions of the underfrequency islanding system in such situations are formulated. Based on the studies conducted by the JSC “Firm ORGRES” at a number of power plants, engineering solutions for the automatic separation of TPP auxiliaries are proposed.
