Summary

The PDPS (Power Equipment Diagnosis and Preventive System) monitors the functions and capabilities of major power facilities to prevent breakdown and accident in advance and supports efficient power facility management through equipment records and DB management. This system consists of a sensor, DAU/CCU, and PDPS server. The sensor is applied to the power equipment to acquire the data, the DAU/CCU acquires the data from the field equipment and transmits it to the upper server, and the PDPS server supports the efficient management and accident prevention of the equipment on the basis of acquired information.

Features

  • - Operation of substation equipment and thermal condition monitoring diagnosis
  • - Provides dynamic screen for easy operation and monitoring
  • - Real time trend analysis using data and graphs
  • - Provides the results of analysis obtained from the diagnosis algorithm
  • - Records of trends and events are kept and managed on large-capacity DB
  • - Supports various reports
