Research and Application of Unit Automatic Monitoring Integration Based on Grid Side in Gas Turbine Power Plant

Abstract

Abstract In view of the original independent grid-related parameters scattered in electrical and thermal equipment, such as the AVC, PMU, primary frequency and DCS, this paper improves the operation reliability of grid-connected power plant equipment, achieves the visualization and retrace ability of grid-related parameters through the centralized monitoring, multidimensional, real-time tracking, intelligent alarm, report customization and log function. Secondly, using these real-time big data, the primary frequency regulation index of the unit is calculated and analyzed in real time, which improves the authenticity and correctness of the primary frequency regulation and AVC, thus to ensure the regulation performance and the stability of the output power frequency.
