Why does a generator experience loss of excitation?

The traditional criteria for loss-of-excitation protection mainly include four key elements: 1. Low-voltage criterion for the generator rotor, which encompasses both constant excitation voltage and variable excitation voltage criteria. 2. Stator impedance criterion at the generator terminal, covering the characteristics of the asynchronous boundary impedance circle and the static stability boundary impedance circle. 3. Two-phase simultaneous low-voltage criterion, comprising the terminal low-voltage criterion and the high-voltage side low-voltage criterion of the main transformer. 4. Reactive-power-inversion criterion, which identifies loss-of-excitation faults by detecting reverse reactive power along with stator overcurrent conditions. The primary differences among various loss-of-excitation protection schemes lie in their distinct protection trip conditions, time delays, or the specific combinations of criteria used.

Outlook for Foreign Trade Trends in the General Equipment Manufacturing Industry

According to a forecast by Zhongyan Puhua, China's general equipment industry is expected to surpass the critical RMB 1 trillion mark by 2030, while its global market share continues to rise. In this ongoing reshuffling of the global industrial landscape, companies must wield technological innovation as their spear and rely on robust compliance systems as their shield, carving out differentiated competitive advantages in the fast-paced arenas of intelligentization, green development, and service-oriented transformation. Only then can they seize the initiative in the trillion-dollar market restructuring—and ultimately achieve a transformative leap from "scale expansion" to "value reconfiguration."
