The invention discloses a network source coordination network-related parameter distributed acquisition and centralized transmission device, which comprises a communication host and a plurality of acquisition units, and a master-slave structure is adopted, the acquisition unit acquires excitation system information and speed regulation system information of the generator set and uploads the information to the communication host; the communication host carries out summarization, edge calculation and analysis processing on the information uploaded by the acquisition unit and uploads a result soas to realize centralized summarization and processing of the acquired data, and at the same time, a dynamic / steady-state data dual-channel separation transmission technology is adopted to ensure thathigh-density network-related data is reliably transmitted to a monitoring background. The device can collect real-time dynamic data, operation states, grid-related parameter constant values and the like of a unit excitation system and a speed regulation system, realizes continuous monitoring of a generator control system, provides effective technical conditions for fault prevention and system analysis, and data source support is provided for advanced applications of a dispatching master station and a power plant monitoring background.
