Grid-connected management system of power generator set

Abstract

The invention discloses a grid-connected management system of a power generator set. The grid-connected management system comprises a power generator set automatic adjustment parameter system, an automatic grid-connected measurement and control system, a human-computer interaction system and a remote monitoring and diagnosis cloud platform system, wherein the power generator set automatic adjustment parameter system, the automatic grid-connected measurement and control system, the human-computer interaction system and the remote monitoring and diagnosis cloud platform system are connected by aCAN bus, the power generator set automatic adjustment parameter system comprises a power generator monitoring module, a sensor group and an executing mechanism, the power generator set automatic adjustment parameter system is connected with a corresponding power generator by a corresponding signal line, and the automatic grid-connected measurement and control system comprises a nine-path high-speed A / D converter, a signal processing circuit, a micro-processing unit, a CAN bus transceiver, a driving circuit and a circuit breaker. By the grid-connected management system, the switching of the power generator is rapid, reliable and safe, and the grid-connected management system has high reliability and high cost performance, is simple to maintain and easy to upgrade and can be applicable to different environments.

Description

technical field [0001] The invention relates to the technical field of grid-connected generators, in particular to a grid-connected management system for generator sets. Background technique [0002] At present, with the continuous deepening of power system reform, improving the reliability of generating units and reducing maintenance costs will be the goals that power generation companies are constantly pursuing. Before the birth of the unit automatic grid connection management system, it was necessary to have professionals in the electric control room for real-time monitoring and manual operation to achieve grid connection, and when a unit fails, the staff cannot immediately switch to the standby unit and Cut off the faulty unit, causing huge losses. The research and development of the grid-connected system of generator sets is conducive to the safe and stable operation of the power grid, reducing the risk of large-scale power outages, improving the self-healing ability o...
