Read OnMonitoring and diagnosis of coal mill systems are critical to the security operation of power plants. The traditional data-driven fault diagnosis methods often result in low fault recognition rate or even misjudgment due to the imbalance between fault data samples and normal data samples. In order to obtain massive fault sample data effectively, based on the …
Read OnChina's heaviest power users are open to potentially unlimited increases in rates as part of last year's reforms to address the energy shortages that struck in the fall. It means that if Beijing can't keep a lid on coal prices, the nation's industrial base will be far less protected from higher power costs than it would otherwise have been.
