Integrated monitoring of hydroelectric generators based on Community Intelligence
Zhaohui Li · Dianli zidonghua shebei · 2013
The framework of integrated monitoring of hydroelectric generators based on CIA(Community Intelligence Agent) model is introduced,which is made up of the CIA system in control domain and the CIA system in maintenance domain.The CIA model contains the message processing layer,behavior control layer and core functional layer,and each CIA contacts with external module(such as other CIAs) through Request message or Report message.The interaction,collaboration,associated action and data sharing among all CIAs in maintenance domain are realized via the real-time field bus(such as CAN bus) or Ethernet.The state data of whole hydroelectric generators are divided into the sampled data,transient data,detailed data and summary data,for which the selectively intelligent storage is applied to improve the pertinence and validity of state analysis and fault diagnosis with less storage space.The real-time interaction,collaboration,associated action among CIAs in monitoring system and the state data fusion of hydroelectric generators are realized through the time fusion,operating condition fusion,abnormal event fusion and conflict resolution strategy,which effectively guarantees the relevance of operating states from different subsystems of hydroelectric generators.
