Description

Technical Field

[0001] The present invention belongs to the technical field of energy storage power stations, and in particular relates to a safety management system for energy storage power stations. Background Art

[0002] Energy storage power stations are a new type of energy system that can store electricity and release it when needed, effectively alleviating the imbalance of electricity in time and space. The application of energy storage power station technology runs through all aspects of power generation, transmission, distribution, and power consumption in the power system, and plays an important role in peak shaving and valley filling, smoothing output fluctuations, and microgrid regulation.

[0003] A typical energy storage system is mainly composed of a battery system, a battery management system BMS, an inverter, a transformer and an energy storage main control system EMS, and most of them are outdoor container-type, which makes it difficult for operation and maintenance personnel to supervise in real time. In addition, the rapid development of energy storage power stations in recent years has led to frequent safety problems and fires, causing huge economic losses and environmental pollution. Therefore, the power station safety management system is particularly important and is an important monitoring method for power station managers to ensure the safe and stable operation of batteries.

[0004] Existing energy storage power stations have independent fire control systems and battery management systems, making it impossible to achieve system linkage and data coupling. In addition, the design of the fire and battery management systems focuses on fire extinguishing and safety alarms, and early warning is impossible. Summary of the invention

[0005] The purpose of the present invention is to provide a safety management system for an energy storage power station, which can provide early warning for unsafe factors in the power station and improve the safety and reliability of the power station.

[0006] The technical solution adopted by the present invention is: Energy storage power station safety management system, including data module, communication module, intelligent multi-data coupling platform, human-computer interaction module and safety action execution module; The data module is used to receive and store all the operating data of the system, and transmit the data to the intelligent multi-data coupling platform for analysis; the communication module is used to transmit data and instructions between modules; the intelligent multi-data coupling platform is used to collect fire protection data in the battery compartment, send the collected data to the data module for storage, and then use the data saved by the data module to perform risk trend analysis, send an alarm signal to the human-computer interaction module, and send instructions to the safety action execution module; the human-computer interaction module is used to receive the alarm signal issued by the intelligent multi-data coupling platform and issue an alarm, and is used for operation and maintenance personnel to issue instructions to the safety action execution module; the safety action execution module is used to receive and execute instructions from the intelligent multi-data coupling platform and the human-computer interaction module.

[0007] The present invention is also characterized in that: The data received and stored by the data module include fire protection data collected by the intelligent multi-data coupling platform, battery voltage, current, and output power data collected by the battery EMS system, as well as daily alarm logs and operation logs of the human-computer interaction module.

[0008] The communication module sends the fire data collected by the intelligent multi-data coupling platform to the data module, and sends the battery voltage, current, and output power data collected by the original EMS system of the battery to the data module; uses the modbus communication protocol to process the historical data stored in the data module, and transmits the data to the intelligent multi-data coupling platform for analysis; transmits the alarm signal issued by the intelligent multi-data coupling platform after analyzing the data to the human-computer interaction module, and transmits the instructions issued by the intelligent multi-data coupling platform after analyzing the data to the safety action execution module; transmits the instructions issued by the operation and maintenance personnel in the human-computer interaction module to the safety action execution module.

[0009] The intelligent multi-data coupling platform uses AI and big data coupling to analyze risk trends. It includes two modules: a fire warning module and a battery safety monitoring module. The fire warning module is used to collect external operating status data of the battery pack and monitor the external operating status of the battery pack, and the battery safety monitoring module is used to analyze the internal operating status of the battery pack.

[0010] The fire warning module consists of four parts: data acquisition unit, video monitoring unit, combustion product monitoring unit and battery pack operation status external monitoring unit; The data acquisition unit uses an infrared camera to collect the internal ambient temperature of the battery compartment, uses a temperature sensor to collect the external temperature of the battery pack, and uses a sound collector to collect the battery operation sound in the battery compartment, and sends the collected data to the data module; The video monitoring unit uses infrared / visible light cameras to monitor the internal operating status of the battery compartment and intelligently identify flames. It also accepts manual fixed-point observations by operation and maintenance personnel in the human-computer interaction module. The video data collected by the video monitoring unit is also sent to the data module for storage. The combustion product monitoring unit is connected to the human-computer interaction module and the safety action execution module. It analyzes the smoke components at the initial stage of the fire through the nitric oxide monitoring sensor and smoke sensor installed on the inner wall of the battery compartment. If there is any abnormality, it will directly send an alarm to the human-computer interaction module and issue an instruction to the safety action execution module to cut off the power supply and isolate it. The external monitoring unit for the battery pack operating status uses the internal temperature, sound and video data of the battery compartment saved by the data module, and compares it with the normal operating sound and normal operating temperature of the battery compartment. The AI ​​analyzes the abnormal status of the sound monitoring and the abnormal temperature rise trend of the battery compartment. If an abnormal situation occurs, an alarm message is generated in time and sent to the human-computer interaction module to issue an alarm.

[0012] The battery safety monitoring module uses the battery EMS data saved by the data module to analyze the internal risk trend of the battery pack and issue an alarm. It includes a battery failure trend analysis unit and a historical data battery health assessment unit; The battery fault trend analysis unit uses the battery pack internal current and voltage, output power data and real-time battery internal temperature data stored in the data module, combined with the battery external temperature monitoring data collected by the fire warning module, to analyze and locate the battery module with abnormally high temperature; The historical data battery health assessment unit includes two parts: system operation status diagnosis and battery health status diagnosis. The historical data stored in the data module is the basis for the unit to perform battery operation diagnosis and battery health diagnosis. These data are used to evaluate the battery's operating status and overall performance. If the battery health is lower than the set value, an alarm will be sent to the human-computer interaction module through the intelligent multi-data coupling platform.

[0013] The human-computer interaction module is arranged in the centralized control center.

[0014] The safety action execution module is the action control and execution module of the internal protection device of the battery compartment, which includes two parts: battery compartment power-off protection and fire protection system control. It automatically cuts off power and isolates the battery when the current and voltage data of the energy storage battery are abnormal. When the operation and maintenance personnel control and the intelligent multi-data coupling platform judge that there is a fire risk, it controls the fire protection system to take corresponding actions.

[0015] The beneficial effects of the present invention are: The safety management system of the present invention couples the battery safety monitoring data and fire monitoring data of the energy storage power station for comprehensive analysis. Compared with the existing independent fire protection system and single battery current / voltage monitoring of the current energy storage power station, the system of the present invention utilizes multi-data coupling and AI intelligent judgment to shift the focus of safety risk and fire risk detection from fire fighting and safety alarms to early warning, changing passive safety processing to active safety prevention, and changing single current monitoring to comprehensive judgment of multi-source data coupling, which can improve the safety and reliability of the energy storage power station and effectively prevent the occurrence of accidents in the energy storage power station.

[0018] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1 The energy storage power station safety management system of the present invention is as follows: Figure 1 As shown, it includes a data module, a communication module, an intelligent multi-data coupling platform, a human-computer interaction module and a safety action execution module.

[0020] The data module is used to receive and store all the operating data of the system, and is the basis for data analysis and risk trend assessment. The communication module is used to transmit data and instructions between modules. The intelligent multi-data coupling platform is used to collect fire protection and battery data, and analyze the data and issue risk trend warnings in combination with the historical data stored in the data module. The human-computer interaction module is used to receive warnings and issue alarms issued by the intelligent multi-data coupling platform, and is used for operation and maintenance personnel to issue instructions to the safety action execution module. The safety action execution module is used to receive and execute instructions from the intelligent multi-data coupling platform and the human-computer interaction module.

[0021] The data module is used to receive and store all system operation data, including fire protection data collected by the intelligent multi-data coupling platform, battery voltage, current, and output power data collected by the battery EMS system, as well as daily alarm logs and operation logs of the human-computer interaction module.

[0022] The communication module includes tangible and intangible connections between modules, and is the carrier of data communication in the energy storage power station. The communication module uses the modbus communication protocol to process the historical data stored in the data module, and transmits the data to the intelligent multi-data coupling platform for analysis; transmits the alarm signal issued by the intelligent multi-data coupling platform after analyzing the data to the human-computer interaction module, and transmits the instructions issued by the intelligent multi-data coupling platform after analyzing the data to the safety action execution module; transmits the instructions issued by the operation and maintenance personnel in the human-computer interaction module to the safety action execution module; sends the fire data collected by the intelligent multi-data coupling platform to the data module; and sends the battery voltage, current, and output power data collected by the original EMS system of the battery to the data module.

[0023] The human-computer interaction module is arranged in the centralized control center. It receives the alarm signals from the intelligent multi-data coupling platform and issues an alarm to remind the operation and maintenance personnel. In addition, the operation and maintenance personnel can issue instructions to the safety action execution module through the human-computer interaction module, including battery power-off isolation instructions, instructions for triggering the fire protection system when a fire occurs, etc. The safety action execution module controls the protection device inside the energy storage battery compartment to perform corresponding actions.

[0024] The safety action execution module is the action control and execution module of the internal protection device of the battery compartment, including two parts: battery compartment power-off protection and fire protection system control. It receives and executes instructions from the intelligent multi-data coupling platform and the human-computer interaction module. When the current and voltage data of the energy storage battery are abnormal, it can automatically cut off the power and isolate it. It can also control the fire protection system to take corresponding actions when the operation and maintenance personnel control and the intelligent multi-data coupling platform trend analysis determines that there is a fire risk.

[0025] The intelligent multi-data coupling platform is used for the collection, analysis and risk trend assessment of fire data. It is based on multi-operation data (including current, voltage, etc.) and monitoring data (ambient temperature, sound, etc.), and uses intelligent means such as AI and big data coupling to assess fire risks and safety risks, send warning information to the human-computer interaction module, and issue action instructions to the safety action execution module. The platform consists of two modules: a fire warning module and a battery safety monitoring module. The fire warning module is used to collect the external operating status data of the battery pack and monitor the external operating status of the battery pack, and the battery safety monitoring module is used to analyze the internal operating status of the battery pack.

[0026] like Figure 2 As shown, the fire warning module includes four parts: a data acquisition unit, a video monitoring unit, a combustion product monitoring unit and a battery pack operating status external monitoring unit.

[0027] The data acquisition unit uses an infrared camera to collect the ambient temperature, a temperature sensor to collect the external temperature of the battery pack, and a sound collector installed in the battery compartment to collect the battery operation sound, and sends the temperature and sound data to the data module. The temperature sensor is arranged as follows: Figure 3 As shown, it is arranged at the center above each battery pack 1 in the battery compartment. At present, the temperature monitoring of the energy storage power station is limited to the battery compartment as a whole, and the temperature monitoring of a single battery pack is not realized. It has a certain hysteresis and is easy to cause delays in data transmission. The system of the present invention improves the method of temperature data collection under the fire protection module, and proposes to set an independent temperature monitoring at the center above each battery pack 1 to replace the overall battery compartment temperature monitoring, and ensure the real-time data transmission of each battery pack temperature measurement point through the communication module. The specific measurement point arrangement is as follows Figure 3 As shown, a temperature sensor 3 is arranged directly above each battery pack 1 in the battery cluster unit 2 .

[0028] The video monitoring unit uses an infrared / visible light camera to monitor the internal operating status of the battery compartment and intelligently identify flames. It also accepts manual fixed-point observations by the operation and maintenance personnel in the human-computer interaction module. A slide rail is set in the center of the top of the battery compartment, and the infrared / visible light camera is set on the slide rail, which slides once every hour. The video data collected by the video monitoring unit is also sent to the data module for storage.

[0029] The combustion product monitoring unit is connected to the human-computer interaction module and the safety action execution module. It analyzes the smoke composition at the initial stage of fire through the nitric oxide monitoring sensor and smoke sensor installed on the inner wall of the battery compartment. If there is any abnormal situation, it will directly issue an alarm to the human-computer interaction module and issue an instruction to the safety action execution module to cut off power and isolate it.

[0030] The external monitoring unit for the battery pack operating status uses the internal temperature, sound and video data of the battery compartment saved by the data module, and compares it with the normal operating sound and normal operating temperature of the battery compartment. The AI ​​analyzes the abnormal status of the sound monitoring and the abnormal temperature rise trend of the battery compartment. If an abnormal situation occurs, an alarm message is generated in time and sent to the human-computer interaction module to issue an alarm.

[0031] like Figure 4 As shown, the battery safety monitoring module includes a battery failure trend analysis unit and a historical data battery health assessment unit. The module uses the battery EMS data saved by the data module to analyze the internal risk trend of the battery pack and issue an alarm.

[0032] The battery fault trend analysis unit uses the operating data such as the internal current and voltage of the battery cluster, output power, and real-time temperature data of the battery stored in the data module, combined with the external temperature monitoring data of the battery collected by the fire warning module, to analyze and locate the battery module with abnormally high temperature.

[0033] The historical data battery health assessment unit includes two parts: system operation status diagnosis and battery health status diagnosis. The historical data stored in the data module is the basis for the unit to perform battery operation diagnosis and battery health diagnosis. These data are used to evaluate the battery's operating status and overall performance. If the battery health is lower than the set value, an alarm will be sent to the human-computer interaction module through the intelligent multi-data coupling platform.
