A Method and Device for Identifying the Power Type of a Mobile Communication Base Station
[Purposes]When the mobile communication base station needs to ensure the power supply unit for power generation due to various reasons,the tower company needs to carry out risk control of power generation costs,prevent fraudulent power generation,and obtain subsidies for power generation costs.[Methods]The voltage frequency of the mains power supply is more stable than that of the oil gen-erator,and the power supply identification model is constructed by comparing the difference between the voltage frequencies of the two power supplies.[Findings]A power supply type identification device based on voltage waveform difference was developed to accurately identify the mains power supply and diesel generator power supply,and to prevent the mains power supply from being used as generator power supply or the generator power supply under normal mains power.[Conclusions]Through simula-tion and on-site installation test,the device can accurately identify the power supply type of the base sta-tion,meet the demand of tower company for risk management and control of power generation costs,and help reduce the operation and maintenance power generation expenses.
