CET-6602 distributed generation local monitoring station is an intelligent monitoring and intelligent operation and maintenance management server independently developed by CET.
It integrates the functions of "server software" and localized one-click lightweight deployment, without the need to go to the cloud, more conveniently grasps the real-time operation status of the new energy power generation system, discovers the hidden problems of the new energy power generation system in advance, helps the efficient and intelligent operation and maintenance of the new energy power station, and makes every kilowatt-hour of renewable power generation more safe and reliable.
Local real-time monitoring of new energy power generation systemThe real-time operation data and real-time working status of each equipment in the new energy power generation system are monitored to achieve comprehensive perception of the underlying equipment.
Early fault diagnosis** of photovoltaic systemsBecause the inherent faults of photovoltaic cells are hidden inside the photovoltaic panels, it is difficult to identify with the naked eye and difficult to react in the short term. Through the dynamic analysis of the current consistency between the parallel PV strings and the current extreme difference between the strings, the platform locates the PV strings that may have problems such as hot spots, hidden cracks, and power attenuation, and actively sends out alarm messages, so as to remind the operation and maintenance personnel to deal with them in time to ensure the healthy operation of the PV power generation system.
The dispersion rate of the output power of the inverter can characterize the consistency and stability of the overall operation of each inverter of the photovoltaic power station, as well as the operation and maintenance level of the photovoltaic power station.
Through the dynamic analysis of the output power dispersion rate and output power extreme difference between each inverter, the platform locates the PV inverter that may have a low utilization rate and takes the initiative to send out alarm information, and reminds the operation and maintenance personnel to deal with it in time to ensure the efficient operation of the PV power generation system.
Energy storage system operation analysis and charging and discharging process evaluationDuring the operation of the energy storage system, each group of single batteries will generate a large amount of operating data. Through the analysis of operation data, the overall operation of the energy storage system can be grasped, and the analysis data for analysis and decision-making can be provided for operation and maintenance personnel.
Through the real-time monitoring of SoC, SOH, charge and discharge times, cycle times, charge and discharge efficiency and other data of each energy storage battery pack, the platform calculates and analyzes the mean value and curve, extreme difference and curve, variance value and curve of real-time cell voltage, real-time cell temperature, real-time cell internal resistance and other data of each energy storage battery pack, analyzes the hidden dangers that may exist in the process of battery operation, and provides important information in a timely manner.
In the process of charging and discharging energy storage batteries, especially lithium-ion batteries, the consistency of cell voltage and cell temperature should not exceed a certain range. The platform calculates, analyzes and evaluates the cell voltage range, cell temperature range, charge and discharge duration, and charge and discharge depth of each charge and discharge process of the energy storage battery pack, locates the battery pack with potential hidden dangers and takes the initiative to send out alarm information, and reminds the operation and maintenance personnel to deal with it in time to ensure the safe operation of the energy storage system.
Intelligent regulation and control of energy storage systemWith the underlying edge controller, the energy storage charging and discharging control strategy can be remotely and flexibly configured from the platform and delivered to the energy storage unit to execute the set charging and discharging strategy. It includes the charging and discharging plan curve of the remote configuration energy storage system, the strategy of remote start and stop energy storage system, etc., to improve the operation and maintenance efficiency of the energy storage power station.
The CET-6602 distributed generation local monitoring station adopts the local "integrated autonomous station + new energy master station" mode, which does not need to be clouded, and is more convenient to realize the comprehensive perception of the new energy power generation system. Real-time operation data analysis and early warning of potential hidden dangers of photovoltaic power generation system, so as to realize the intelligent operation and maintenance and management of photovoltaic power generation; Diagnosis and analysis of the state of health of energy storage batteries, intelligent control of charge and discharge, to create an advanced and reliable energy storage system; Analysis of new energy system operation curves, operation report viewing, and closed-loop event management to improve the operation and maintenance efficiency of new energy power generation systems.
