Photovoltaic power generation monitoring and management system

       Photovoltaic power generation monitoring and management system, via the combined action of data acquisition and monitoring analysis, transfer the terminal hardware devices and optimizing the configuration, effectively integrates power generate equipments, thus reducing the resource consumption and waste in photovoltaic power generation and management, and reducing the investment and operation cost of building websites. Effective data integration and analysis, and historical data report management are the decision basis of power station’s operation and plan, that can help power station achieve the goal of promoting management level.

  Remote monitoring, operation and maintenance management are efficient and convenient means of interior unified coordination and interaction, to achieve that events can be informed and failure can be maintained. Reduce operation and maintenance cost, and improve treatment efficiency at the same time.

Functions Introduction

       Photovoltaic power generation monitoring and management system, is composed of the following three modules.

Product architecture

Function list

       【A acquisition monitoring subsystem

       1 Data real-time collection: (1) real-time collection of global equipments: such as tracking array, inverter, meteorological station, anemograph, DNI, GHI, electricity meter, optical monitoring instrument and network equipment. Make continuous data collection for outdoor test base power station. (2) Abundant protocol libraries: Modbus RTU/TCP, IEC 101, IEC 102, IEC 103, IEC 104, CDT

       2 Real-time monitoring management: observe the operational aspect and state of global equipments continuously, and can be showed by image, sheet, trend curve chart, pie chart, histogram, etc.

       3 Remote operation monitoring and controlling: remote monitor integral operational aspect, remote monitor operational aspect of standard cell, remote control equipments. Also known as remote signaling, remote metering, remote control.

       4 Data store-and-forward: stored data includes record data, real time data, and historical data. Store and transmit local sunlight, temperature, wind speed and wind direction, and other meteorological information. And monitor, record, store and transmit operation parameters and operation states of modules.

       5 Mobile monitoring management: real-time look over operation state of power station, u operational aspect and statistical analysis performance data of unit and array via mobile terminal (mobile phone, tablet PC).

       【B operation and maintenance management subsystem

       1 System management: (1) daily functions: user management, resource management, safety management, log management, configuration management (2) practical miscellaneous functions: work order management, work order plan, knowledge base (FAQ and malfunction) help and management

       2 Device layout: communication link configuration, standard cell configuration, data and linkage configuration of standard cell

       3 Monitoring page configuration: provide data association via mechanism based on pixel

       4 Alarm events linkage: when receive the alarm information of real-time event, remind operation staff with linkage based on strategy, such as sound-light alarm, short-message warming.

       5 Log operation tracking: the system can record users’ log-in information automatically, such as log-in user, log-in time, exit time, and operated functions. And also can record the processed time, data range, and executive condition of data entry, data synchronization, data extractions, data analysis and other applications automatically, convenient for tracking and auditing when the system goes wrong.

       【C analytical prediction subsystem

       1 Analytic and statistics of statement: do statistical analysis of the real-time state and historical data in the field. Generate statistical analysis and statement of field failure events rapidly.

       2 Statistic analysis of data: do statistical analyze of electricity generation’s situation and operational aspect, such as generating capacity, operational days, saved standard coal, CO2 emission reductions, etc., and then support operational analysis of power generation enterprises, satisfy the demand of data analysis and process for power station. And the data which be concerned by user can freely generate form, curve chart, histogram, etc.

       3 Multiple warming safeguard: can set multiple alarming types, such as out-of-limit, misoperation, communication failure, environment failure, equipment installation failure, etc., and also can configure performance parameters, so that generate performance warming event, such as overvoltage and overcurrent event.

       4 Forecast electricity generation in short time: forecast generating capacity in short on the basis of atmosphere and field operation data.

       5 Recall historical events and excavate failure: support recalling failure, so that can show the generating process of failure intuitively, and provide event service for upper viewing and analysis. It is convenient for user to track events via filter the events on the basis of type, time, operator, or other conditions.
