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.
| PDPS Station | Normal monitoring and data record management | |
|---|---|---|
| Data acquisition unit (DAU) | Transmit the signal acquired from various sensors to the upper system | |
| Sensors | Partial discharge sensor | Early detection of partial discharge signal arising within GIS |
| Gas density sensor | Monitor the leakage and lowering of GIS gas density | |
| Leakage current for lightning rod | Analyzes the harmonic current flowing through the lightning rod and determines the deterioration | |
| Analysis of gas in oil | TR gas in liquid is analyzed in real time for early diagnosis | |
| Wiring insulation oil temperature | The TR wiring / insulation liquid temperature is compared and analyzed to determine overload and abnormality | |
| On-line monitoring diagnosis | Indication of abnormality for each diagnosis category of TR and GIS for each Bay Detailed information providing screen for each diagnosis category GIS PD measurement and 2D / 3D analysis screen Real time event and information screen indication Real time communication condition |
|---|---|
| Convenience of operator | Monitoring screen editing Communication device On-line setting Filtering function for record inquiry Excel-based report preparation |
| Preventive diagnosis analysis | Precise diagnosis of gas in liquid for specialized DB base Neural Network, precise diagnosis of PD based on fuzzy algorithm |
