CONSTRUCTION OF GENERATOR CAPABILITY CURVE Figure 6: Capability diagrams for generator GTHW-360: curve from manufacturer's documentation () significantly deviates from the curve obtained during tests (---)
Conclusion • It has been established that manufacturers' P-Q curve for generator GTH 360 gives overestimated reactive power values by 2%, 4% and 6%, for reduced active power: 250MW(0.71P G,N ), 200MW( 0.581P G,N ) and 50MW, respectively. • Similar deviations were observed during the extensive testing and research for newer generators in the U.S. • Therefore, it is recommended to update P-Q curves every 5-6 years or after major repairs.
