Abstract

The invention provides a photovoltaic power station online monitoring method and system based on an order reduction-distributed cloud algorithm. The method comprises the steps of establishing a mathematical model, wherein a mathematical model of the photovoltaic power station is established based on a mathematical model of a power generation unit of a single inverter; carrying out model processing, wherein block separation processing is performed on the photovoltaic power station mathematical model according to peripheral factors; performing a block separation and order reduction step, whereinafter the photovoltaic power station is started up, the sampled data monitored in real time is input into the mathematical model of the photovoltaic power station to obtain a state matrix, and blockseparation and order reduction treatment is carried out on the state matrix to obtain a plurality of sub blocks; and performing distributing calculation, wherein the obtained sub blocks are distributed to different virtual work stations for calculation, and the calculation results are summarized and output. According to the method, the changeable large-scale matrix characteristic values can be accurately tracked and solved in real time, and real-time monitoring of the operation state of the large-scale photovoltaic power station is realized.

Description

technical field [0001] The invention relates to the field of power station monitoring, in particular to an online monitoring method and system for a photovoltaic power station based on a reduced-order-distributed cloud algorithm. Background technique [0002] At present, many real-time photovoltaic power station monitoring methods and systems can realize real-time monitoring of location information, power generation information, and weather information of large-scale photovoltaic power stations, but they are all judged based on real-time data results, and cannot detect potential errors of photovoltaic power stations. stable mode. There are inevitable gaps in the treatment and prevention of oscillation accidents. [0003] Therefore, this real-time observation method in the prior art (the Chinese patent application number "CN201810792077.5" discloses "monitoring method and system for photovoltaic power plants") can observe the operating information of photovoltaic power plant...
