Optimization and Application of Long-Distance Power Supply Scheme for Coal Mine Underground Mining and Excavation Workfaces
Abstract：To solve the series of power quality problems in long-distance power supply, such as low voltage at the end of the line, voltage fluctuations, and waveform distortion, caused by the extension of the distance of coal mine mining and excavation workfaces, the increase in the number of electrical equipment, and the increase in power. By adopting voltage compensation and impedance voltage drop adaptive algorithms, and establishing a comprehensive regulation model for long-distance compensation based on in-field tests and field measurements, the power quality issues in long-distance power supply can be solved without using traditional measures such as parallel cables or mobile transformers. This achieves a long-distance power supply of 3,000 meters for the excavation workface and 5,000 meters for the mining workface.
