分布式风电场设备多智能体状态监测系统

Condition Monitoring System of Equipments in Distributed Wind Farm Based on Multi-agent System

针对风电场监测系统结构模块化设计以及底层硬件与顶层软件系统耦合的问题,设计分布式风电场设备状态监测系统。为实现软硬件解耦,应用多智能体系统技术,增减监测对象无需变动顶层软件;同时采用傅里叶变化加小波分析方法处理各设备运行数据。该系统由两层构成:底层为数据采集及预处理系统,由各风电机组的传感器和嵌入式系统组成;顶层是面向整个风电场的数据管理系统,结合了各机组底层传感单元及预处理系统的分散特性。实际风电场运行试验结果表明,该系统能实时监测风电机组各基本单元的运行状态,且机组各运行单元之间及机组之间的监测相互独立、互不影响。

Aiming at problems of modular design of wind farm monitoring system and coupling of its bottom hardware and top software systems, this paper introduces design for condition monitoring system of equipments in distributed wind farm. For realizing decoupling of hardware and software, it proposes to use multi-agent system technology to increase or decrease monitoring objects while dispensing with changing top software, meanwhile, it suggests to use Fourier transform and wavelet analysis method to deal with various operational data. This system composes of two layers including bottom layer which is a kind of data acquisition and pretreatment system consisted of sensors and embedded systems of wind power units, while the top layer is a kind data management system oriented the whole wind farm which combines dispersion characteristics of sensor units and pretreatment systems. The practical trial operation testing of the wind farm shows that this system can monitor operation condition of each basic unit of the wind power unit in real time and monitoring between each operational unit is independent without interference.
