For normal grid frequency operation, fluctuations above or below the standard should not exceed ±0.2 Hz. According to regulations issued by China's Ministry of Power Industry, when the frequency drops below 49.5 Hz, it can last for no more than 60 minutes. If the frequency falls below 49.0 Hz, it should not exceed 30 minutes. These limits are crucial because frequency variations not only impact the internal operations of the power system but also affect households and industries in different ways. When the frequency drops to 48 Hz, motor speeds decrease by approximately 4%, which can lead to reduced output in many industrial processes and compromise product quality. Maintaining a stable frequency at the rated level is essential for the reliable operation of both the power grid and the devices connected to it. This stability ensures efficient energy distribution, prevents equipment damage, and supports the overall performance of electrical systems across the country.
