        How to deal with the alarm signal of microcomputer harmonic elimination device

        AddTime:2020-07-29 11:16:45   Views:     【 Big Mid Small 】   Print   Close

        The microcomputer harmonic elimination device uses microcomputer technology to eliminate the resonance of power grid. The fast Fourier analysis is realized by using the computer's fast and accurate data processing ability, and its frequency selection is accurate. Through the acquisition of Pt open delta voltage, the various frequency components of power grid resonance are analyzed quickly and accurately: 1. Single phase grounding; 2. Transition process; 3. Grid resonance. If it is resonance, the computer sends out instructions to put the harmonic elimination circuit into operation to realize the function of fast harmonic elimination.

        Safe and reliable power supply system is the most basic requirement of enterprise development. The safety and reliability of power supply system must be supported by reliable power supply equipment. However, the power supply equipment will have different degrees of failure under the influence of the environment, troubleshooting is the key to ensure safe power supply, and the fault point is the most important.

        In the actual operation of microcomputer harmonic elimination, resonance alarm will appear. First of all, the specific situation should be analyzed. Under normal working conditions, the locking state of high-power solid relay in the device with voltage less than 30V will not affect the normal operation of the system. When the voltage is more than 30V, the system will have a fault. The microcomputer will collect data, measure and analyze the signal through the circuit, and filter and amplify the digital signal processing technology. Then the monitored data are analyzed and calculated to get the fault type. There are certain reasons for the resonance. When the intelligent microcomputer harmonic elimination device appears resonance alarm in the process of operation, we should correctly analyze the specific position and reason of resonance, so as to eliminate resonance.
