Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, and relates to a network source coordination online monitoring technology, in particular to a network source coordination network-related parameter distributed acquisition and centralized transmission device. Background technique [0002] Generator excitation system and speed control system are important adjustment equipment for the stable operation of the power grid, ensuring that the generator set provides stable, fast and economical power to the power grid. As important network-related equipment, the speed control system and excitation system are important objects of network source coordination and management. Accurately grasp the mathematical model and characteristic parameters of the excitation system and speed control system of each grid-connected unit, and monitor the operation status of the excitation system and speed control system in real time. One of sex work. However,...
