Embodiment Construction
[0114] Modeling and parameter identification of the prime mover and its governor for a 600MW unit in a power plant, the steps are as follows:
[0115] 1. Data collection
[0116]
[0117]
[0118] 2. Model selection
[0119] The unit is a coal-fired unit. For parameter identification by link, use GX, GK, GA, and TB cards in combination for BPA, and TGOV5 model for PSS / E; for overall parameter identification, use GI\GI+, GA, and TB cards in combination for BPA, and for PSS / E selects the GGOV1 model.
[0120] 3. Carry out field tests in sub-links. Several tests were carried out when the active power of the generator was 450MW, 500MW and 550MW, as follows:
[0121]
