The invention relates to a
system structure of power generation group-level hydro-power
generating unit distributed state monitoring and diagnosis platform construction. The
system structure includes an overall technical architecture, a
business architecture, an information /
data architecture, an application architecture, a technical architecture, infrastructure and the like. According to a platform, based on unified codes, three levels of data centers are established to realize distributed
data acquisition, storage and application; data are divided, pushed and extracted according to data characteristics and application requirements, so that
network communication pressure and data maintenance quantity can be can effectively reduced, and therefore, the real-time performance of the data can be enhanced; application modules of the platform provide an application market which can provide application services for 9 levels of user roles according to needs; and mutual communication and sharing of information such as
monitoring data, control dispatching, diagnosis results and policy-making instructions between a
monitoring and control system, a regional centralized control analysis and diagnosis system and a group monitoring and diagnosis system of a
station can be realized, and solutions can be provided for the power generation group-level hydro-power
generating unit distributed state monitoring and diagnosis platform construction.
