Abstract: Aiming at the problem existing in the data signal acquisition of the traditional integrated power system, the integrated converter board based on the integrated power signal acquisition technology is developed by analyzing the reliability, integration and accuracy. The application results show that the acquisition method is effective to solve the problem of the high error rate of signal acquisition because of the large number of leads and contacts in the panel. The efficient and reliable centralized processing method of data and alarm information is made, which provide some reference for the integrated power signal acquisition and transfer design of the substations.
