Specifically, the monitoring subsystem 2 includes a front data interface, a data exchange interface, a first processing device 21, a second processing device 22, a second storage device 23, and a display device 25.
The front data interface adopts a flexible and transversely expandable cluster front technology, has mass data expansion access capacity, and the monitoring subsystem 2 adopts a cloud deployment mode, so that when the access nodes are increased to a certain extent, the front server nodes are expanded to perform distributed deployment, and the system completes the access of the newly added nodes under the condition that the performance of the original access nodes is not influenced. Specifically, the cluster front-end technology is relative to single-point front-end processor deployment, and a cluster refers to deploying a plurality of front-end processors according to the size of data volume, acquiring the front-end processors meeting preset conditions from a front-end processor routing table according to operation requirements of front-end users, sending the operation requirements to the corresponding front-end processors, and receiving a return requirement result of the front-end processors by the front-end, so that the problem that a single front-end processor is overloaded when the data volume is large can be solved.

It will be appreciated that the functionality of the active operation and maintenance evaluation index system subsystem may be implemented by the second processing device 22.
As an optional embodiment, the process of acquiring the field data of each acquisition point sent by each manager group 1, determining whether the field data of each acquisition point meets the alarm condition corresponding to the acquisition point, and if yes, storing the field data meeting the alarm condition as alarm data in the second storage device 23 includes:
acquiring field data of each acquisition point transmitted by each management cluster 1;
judging whether abnormal data and/or missing data exist in each acquisition point;
if not, determining the field data of the acquisition point as effective data;

and storing the effective data of the acquisition points with the identification bits being the first preset values into a second storage device 23 as alarm data.
Specifically, the first processing device 21 is specifically configured to perform operations such as data cleaning, data analysis, alarm judgment, and state processing on basic data acquired by the distributed photovoltaic power station in real time. Taking a manager group 1 as an example, explaining the process of data processing, firstly cleaning the field data sent by the manager group 1, judging whether the field data of a certain collection point sent by the manager group 1 has overlarge or undersize abnormal data or missing data, if the field data has abnormal data, filtering the abnormal data, and then analyzing the field data of the collection point, namely calculating effective data according to the abnormal data/the field data before and after the missing data or the field data in a period of time, replacing the abnormal data with the effective data or complementing the missing data, and determining the non-abnormal data as the effective data. Then, whether the collection point meets the alarm condition is judged according to the valid data of each collection point, if the valid data is judged to be larger than a certain alarm preset value or smaller than a certain alarm preset value, the flag position corresponding to the collection point meeting the alarm condition is a first preset value, for example, 1, and the identification position of the collection point not meeting the alarm condition is a second preset value, for example, 0, it can be understood that the data corresponding to the collection point set to 1 is the alarm data, and the alarm data is stored in the second storage device 23.
Considering that the management cluster 1 uploads the field data of each collection point of the photovoltaic power station, the field data can also be understood as directly measured data, and for the receiving party of the monitoring subsystem 2, only the field data of the collection point 1, the field data of the collection point 2, and the field data of the collection point 3 can be obtained, therefore, the field data of each collection point also needs to be configured in an associated manner, for example, the field data of the collection point 1 is associated with the power consumption of the station. Furthermore, it is also considered that some indexes of the photovoltaic power station need to be obtained by further calculating the acquired field data, for example, the field data needs to be accumulated, or the field data needs to be multiplied by a correlation coefficient and other calculation operations, and the processed data is stored in the second storage device 23, the acquisition point association operation and the recalculation operation on the field data can be realized by a new processing device, or by the first processing device 21, and the application is not specifically limited herein.
Further, the field data corresponding to each photovoltaic power station and the statistical data obtained by further calculating the field data are sent to the second processing device 22, and the second processing device 22 is used for calculating and analyzing the indexes of each photovoltaic power station.
Specifically, the hierarchical evaluation index system establishes a 7-class 24-class hierarchical evaluation index system shown in fig. 3 by an analytic hierarchy process by analyzing energy characteristics, key equipment and an energy monitoring range of a distributed photovoltaic power station, and the system is divided into two levels, a first-level index and a second-level index;
wherein, the first-level index comprises 7 categories including a light resource index, a clean power index, an energy efficiency index, an energy consumption index, an operation index, an economic index and an energy-saving index.

specifically, in the multi-dimensional index calculation and display, the multi-dimensions include a space dimension and a time dimension, and the space dimension includes different cities, different counties, different power stations, different inverter devices, square matrix devices and component devices; the time dimension includes minutes, hours, days, months, years; the display can be realized by the display device 25 of the monitoring subsystem 2, the display form comprises the transverse comparison of the corresponding time of a certain index of different equipment with the same type of space dimension, and the single index ranking of the corresponding time of the same type of equipment can be directly observed; the display form comprises transverse and longitudinal comparison of a certain index of different equipment with the same type of space dimension in a corresponding time period, and the index change trend of each time in the corresponding time period of the same type of equipment can be directly observed; the display form also comprises the list display of the subordinate secondary indexes of the primary indexes of the similar equipment, and the comparison display of different indexes of the similar equipment can be directly observed; for equipment with brand types, brand screening display can be carried out, and index comparison of equipment with the same brand can be directly observed.
The process that the second processing device 22 judges whether the abnormal indexes exist in the indexes of each photovoltaic power station comprises the step of carrying out dimensionless processing on the same indexes of each photovoltaic power station; determining index ranks of the same indexes of each photovoltaic power station subjected to dimensionless processing, and determining indexes corresponding to the ranks of the next n power stations as abnormal indexes corresponding to the power stations; the abnormality index and the corresponding power station are stored in the second storage device 23.
Specifically, after dimensionless processing is carried out on indexes of each photovoltaic power station according to calculated values of indexes of different dimensions, comparison and analysis are carried out to obtain index ranks of different types of equipment, and therefore the equipment and the power stations with lower ranks are found out. For example, assuming that there are 5 photovoltaic power stations, which are respectively denoted as a, B, C, D, and E, dimensionless processing is performed on the inverter conversion efficiency n of the 5 photovoltaic power stations, then calculated values of indexes after dimensionless processing are ranked, and the order from large to small is nC > nB > nE > nA > nD, then the abnormal indexes are nA and nD, that is, it can be determined that the inverter conversion efficiencies of the photovoltaic power station a and the photovoltaic power station D are low and abnormal, and the abnormal indexes are stored in the second storage device 23, so that the inverter conversion efficiencies of the photovoltaic power station a and the photovoltaic power station D are continuously used as operation and maintenance standards to perform active operation and maintenance, and an equipment operation and maintenance task is distributed to an operation and maintenance post station.
Specifically, the second storage device 23 includes three databases, which are a real-time database (RTDB), a Time Sequence Database (TSDB), and a relational data management system (RDEMS), where the data stored in the real-time database includes data collected on site and valid data processed by real-time computation; the data stored in the time sequence database can be subjected to acquisition point association configuration, and only the configured real-time data is stored; the data stored in the relational data management system includes alarm data, statistical data, measurement data, and application analysis data, where the application analysis data includes various data obtained by the second processing device 22, such as indexes, abnormal indexes, and display data.

It can be understood that the photovoltaic power station with the abnormal index is the photovoltaic power station to be processed, the photovoltaic power station with the alarm data is the photovoltaic power station to be processed, and the corresponding operation and maintenance work order is issued based on the photovoltaic power station to be processed, and the operation and maintenance work order may include the position information of the photovoltaic power station to be processed and the related data (the alarm data and/or the abnormal index) so as to be processed by the subsequent operation and maintenance subsystem 3.

The operation and maintenance work order is distributed by the monitoring subsystem 2, then is processed and decomposed by the operation and maintenance posters at all levels, and then is distributed to the subordinate, the subordinate operation and maintenance posters feed back the completion condition of the work order to the superior posters, and then the completion condition of the work order is counted by the primary operation and maintenance posters and is synchronized to the monitoring subsystem 2. The uploading condition may be that the number of the processing states of the obtained operation and maintenance work orders is the same as the number of the issued operation and maintenance work orders, for example, after the first-stage operation and maintenance post station receives 3 operation and maintenance work orders, the first-stage operation and maintenance post station issues the 3 operation and maintenance work orders, and the processing states of the 3 operation and maintenance work orders are obtained and then fed back to the monitoring subsystem 2.
Specifically, each level operation and maintenance post contains power station archives, equipment platform account, spare parts, operation and maintenance management module.
