[0047] The present application is described in detail below with specific reference being made to certain embodiments. It is to be understood that other embodiments can be used and that the scope of the application is not to be limited to the specific embodiments described below. Various details of the application can be modified in various ways and substituted for one another without departing from the spirit and scope of the application.

[0048] It should be noted that the drawings included herewith are included to illustrate only specific embodiments of the application and are not intended to limit the scope of the application. One skilled in the art will readily recognize from the following description that alternative embodiments of the various aspects of the application can be practiced.

[0049] In the following description, numerous specific details are discussed to provide a thorough understanding of the application. However, one of ordinary skill in the art will recognize that the application can be practiced without one or more of the specific details. In other instances, well-known structures and devices are not shown or described in order to avoid obscuring aspects of the application.

[0050] With the increase of use time, individual or partial storage batteries will have the phenomenon of regressive aging due to the increase of internal resistance. It has been proved that the capacity of the whole storage battery group is subject to the capacity value of the worst storage battery, instead of the average value or the rated value (initial value). When the actual capacity of the storage battery drops to less than 90% of the rated capacity, the storage battery enters the recession period. When the capacity of the storage battery drops to less than 80% of the rated capacity, the storage battery enters the sharp recession period, and the recession period is very short. At this time, the storage battery group has great safety hazards. The storage battery monitoring can realize online monitoring of multiple storage battery groups, timely discovery of the lagging single storage battery, analysis of the actual trend of the storage battery, real-time grasp of the running state of the storage battery, and ensures the reliable and fault-free operation of the backup power supply system.

[0051] In order to solve the technical problems that the running parameters of the storage battery cannot be remotely and real-timely checked, the historical data cannot be stored, and the trend change cannot be automatically alarmed and prompted in the prior art, the application provides a storage battery monitoring system. According to the characteristics that the power consumption load is concentrated, the high-power and long-period electrical equipment is much, the process device needs continuous production, and the transformer substations are mostly unattended in the petrochemical industry, the voltage, temperature, internal resistance and other state parameters of the storage batteries of auxiliary power supplies such as the DC panel, the UPS power supply and the EPS power supply of the transformer substation are monitored in real time. The storage battery monitoring data is converted by the MODBUS protocol and the MODBUS_TCP protocol, the communication medium adopts the RS485 communication cable and the super five category network cable, and is connected to the transformer substation integrated automation system protocol conversion device, so that the storage battery monitoring data is connected to the power dispatching control system. The power dispatching control system displays the storage battery monitoring data of each transformer substation in real time on the monitoring host of the integrated automation monitoring system, and sets the out-of-limit alarm function and the historical sampling function for the storage battery monitoring data.

[0052] It should be noted that the storage battery monitoring system includes two core parts of storage battery state monitoring and fault early warning. According to the characteristics of the storage battery equipment, the data that can clearly reflect the health status of the storage battery are the three state monitoring quantities of voltage, temperature and internal resistance. The internal resistance measured each time of the storage battery is compared with the initial internal resistance of the storage battery. If the current internal resistance is 1.3 times of the initial internal resistance, the capacity of the storage battery may be lower than 80%. According to the Arrhenius rule, the corrosion speed of the storage battery doubles when the temperature of the storage battery increases by 10℃. Therefore, once the temperature of the storage battery increases by 10℃, the service life of the storage battery will be halved. Therefore, by constructing the storage battery monitoring system, the voltage, temperature and internal resistance of the storage battery are mainly monitored in real time and fault early warning is performed. It should be noted that in the embodiment, the storage battery monitoring system is mainly applied to the real-time monitoring of the voltage, temperature, internal resistance and other state parameters of the storage batteries of auxiliary power supplies such as the DC panel, the UPS power supply and the EPS power supply in the 35kV unattended device transformer substation.

[0054] It should be noted that the protocol conversion device 300 is a device for realizing interconnection and intercommunication between different communication protocols. Its core function is to convert data of one protocol into data of another protocol, so as to realize communication between different devices.

[0057] For details, please continue to refer to Figure 2As shown, each TA single battery monitoring module 120 monitors one battery, so the number of TA single battery monitoring modules 120 is the same as the number of single batteries included in the battery pack of the EPS power supply and the UPS power supply. In this embodiment, each TA single battery monitoring module 120 is installed on the corresponding single battery housing, and is connected to the positive and negative poles of the battery through a dedicated connecting wire or clip to obtain the voltage and internal resistance data of the battery, and is in contact with the battery through the built-in temperature sensor to obtain the temperature data of the battery. It is worth noting that each TA single battery monitoring module 120 is cascaded through a communication line to form a complete TA single battery monitoring network. The TC module 130 is installed on the battery rack to collect the charge and discharge current and the ambient temperature of the battery pack, and is connected to the first TA single battery monitoring module 120 of the TA single battery monitoring network at the first end and to the CM convergence module 110 at the second end. It should be noted that the H3G-TA battery monitoring system further includes a first current transformer 140, one end of which is embedded in the cable of the battery pack, and the other end is connected to the third end of the TC module 130, for obtaining the current data of the battery pack. The CM convergence module 110 is installed on the battery rack or in a separate network cabinet, and the transmitting end of the CM convergence module 110 is connected to the receiving end of the protocol conversion device 300 through a super five category network cable, for uploading the voltage data, internal resistance data, temperature data and current data of the battery pack of the EPS power supply and the UPS power supply to the protocol conversion device 300 through the MODBUS_TCP protocol.

[0058] In an example embodiment of the present application, the second type of auxiliary power supply includes a direct current screen.

[0059] In an example embodiment of the present application, please refer to Figure 3As shown, the second monitoring unit 200 comprises a BVSB04 voltage sampling box 220, an MTSB01 temperature sampling box 230 and a ZNH05 master control module 210. One end of the BVSB04 voltage sampling box 220 is connected to each battery of the DC screen through a sampling line, and the other end is connected to the ZNH05 master control module 210 through a communication line, for obtaining the battery voltage data of the DC screen. One end of the MTSB01 temperature sampling box 230 is connected to each battery of the DC screen through a sampling line, and the other end is connected to the ZNH05 master control module 210 through a communication line, for obtaining the battery temperature data of the DC screen. The ZNH05 master control module 210 is connected to the protocol conversion device 300 through an RS485 twisted pair line, for receiving the battery temperature data sent by the MTSB01 temperature sampling box 230 and the battery voltage data sent by the BVSB04 voltage sampling box 220, and sending the battery temperature data and the battery voltage data to the protocol conversion device 300.

[0060] In an exemplary embodiment of the present application, the second monitoring unit 200 further comprises a plurality of TSP01 temperature sensor probes. One end of each TSP01 temperature sensor probe is connected to each battery of the DC screen, and the other end is connected to the MTSB01 temperature sampling box 230, for collecting the battery temperature data of the DC screen.

[0061] Specifically, please continue to refer to Figure 3As shown, the BVSB04 voltage sampling box 220 is arranged near the battery of the DC screen, and is connected with the positive and negative poles of the battery through a dedicated connecting line or cable which needs to be accurately connected to each battery in the battery pack to ensure that the BVSB04 voltage sampling box 220 can collect the voltage data of each battery. The MTSB01 temperature sampling box 230 is also arranged near the battery of the DC screen, and is connected with each battery in the battery pack of the DC screen through a plurality of TSP01 temperature sensor probes for acquiring the temperature data of each battery in the battery pack of the DC screen. It should be noted that the second monitoring unit further comprises a second current transformer 240, one end of which is embedded on the cable line of the battery pack of the DC screen, and the other end is connected with the ZNH05 master control module 210 for acquiring the current data of the battery pack of the DC screen. The sending end of the BVSB04 voltage sampling box 220, the MTSB01 temperature sampling box 230 and the current transformer 240 is connected with the ZNH05 master control module 210 through a communication line, the BVSB04 voltage sampling box 220 sends the acquired battery voltage data of the DC screen to the ZNH05 master control module 210, the MTSB01 temperature sampling box 230 sends the acquired battery temperature data of the DC screen to the ZNH05 master control module 210, and the second current transformer 240 sends the acquired battery current data of the DC screen to the ZNH05 master control module 210. The ZNH05 master control module 210 is connected to the protocol conversion device 300 through an RS485 communication interface, and uploads the battery temperature data, the battery voltage data and the battery internal resistance data calculated by the ZNH05 master control module 210 to the protocol conversion device 300 through a MODBUS protocol, so as to realize the connection with the substation integrated automation system.

[0062] The substation integrated automation system is configured with a protocol conversion device 300, and after the communication interface parameters are correctly set and the configuration is made in the protocol conversion device 300, the battery monitoring data in the DC screen, the UPS power supply and the EPS power supply can be uploaded to the protocol conversion device 300, and the protocol conversion device 300 simultaneously forwards the acquired battery monitoring data to the remote device in real time.

[0063] The motion device is part of a substation integrated automation system, and has the function of uploading integrated automation data of the whole station to a power dispatching control system. Through the remote device, real-time monitoring data of the battery in the switch cabinet can be transmitted to the power dispatching control system in real time. The power dispatching control system displays the real-time monitoring data of the battery in the DC screen, UPS power supply and EPS power supply of each substation on the monitoring host 400 of the integrated automation monitoring system, and sets the out-of-limit alarm function for the battery temperature, internal resistance and voltage data. It is worth noting that the monitoring host 400 can store historical monitoring data of the battery to realize the historical sampling function.

[0064] In an example embodiment of the present application, the out-of-limit alarm includes a battery temperature out-of-limit alarm, a battery internal resistance out-of-limit alarm, and a battery voltage out-of-limit alarm.

[0065] In an example embodiment of the present application, the battery temperature out-of-limit alarm includes: if the monitored battery temperature data exceeds the preset temperature limit value and the over-limit duration is greater than the preset time, an out-of-limit alarm of the battery temperature is issued.

[0066] In an example embodiment of the present application, the battery internal resistance out-of-limit alarm includes: if the monitored battery internal resistance data exceeds the preset internal resistance limit value, an out-of-limit alarm of the battery internal resistance is issued.

[0067] In an example embodiment of the present application, the battery voltage out-of-limit alarm includes: if the monitored battery voltage data is lower than the preset voltage limit value, an out-of-limit alarm of the battery voltage is issued.

[0068] Specifically, the lower the ambient temperature (below 5℃), the worse the battery charging acceptance, and the longer the charging time. The higher the ambient temperature (above 30℃), the more active the internal reaction of the battery, and the more likely to overcharge, and at the same time, the capacity of the battery will also decrease due to the decrease in temperature. Therefore, the ambient temperature should be kept at 15℃-30℃. In this embodiment, the temperature out-of-limit alarm uses a delay algorithm to prevent frequent alarms when the preset temperature limit value is exceeded. In this embodiment, the preset temperature limit value is set to 25℃, the upper limit range is 5℃, the lower limit range is 10℃, and the preset time is set to 60 seconds. When the battery temperature data exceeds the preset temperature limit value and the over-limit duration is greater than the preset time, or the battery temperature data exceeds the upper limit value 30℃ or the lower limit value 15℃, the substation integrated automation system will issue an alarm information and sound to prompt the operator to check the battery operation in time and handle it in time.

[0069] The real-time measured internal resistance of the storage battery is compared with the initial internal resistance of the storage battery, if the current internal resistance is 1.3 times of the initial internal resistance, the capacity of the storage battery can be lower than 80%, the storage battery capacity test or new storage battery needs to be replaced in time, and the overall performance of the storage battery pack is avoided. Therefore, the internal resistance limit adopts a simple algorithm, that is, the internal resistance data measured when the storage battery is put into use is taken as the original data S, and the data of S*1.3 is taken as the preset internal resistance limit value. When the internal resistance data of the storage battery exceeds the preset internal resistance limit value, the substation comprehensive automation system will issue an alarm information and a sound, prompting the operator to check the storage battery operation in time and processing in time.

[0070] If the storage battery is insufficiently charged or the load is too large, the output voltage of the storage battery will decrease, so when the real-time measured voltage of the storage battery is lower than the preset voltage limit value, the substation comprehensive automation system will issue an alarm information and a sound, prompting the operator to check the storage battery operation in time and processing in time.

[0071] In summary, the storage battery monitoring system provided by the utility model, including first monitoring unit 100, second monitoring unit 200, protocol conversion device 300, remote device and monitoring host 400, one end of first monitoring unit 100 is connected with the storage battery of first auxiliary power supply, the other end is connected with protocol conversion device 300, be used for obtaining the storage battery monitoring data of first auxiliary power supply, one end of second monitoring unit 200 is connected with the storage battery of second auxiliary power supply, the other end is connected with protocol conversion device 300, be used for obtaining the storage battery monitoring data of second auxiliary power supply, protocol conversion device 300 is connected with remote device and monitoring host 400 respectively, protocol conversion device 300 is used for receiving the storage battery monitoring data obtained by first monitoring unit 100 and second monitoring unit 200, and the storage battery monitoring data is sent to remote device and monitoring host 400, remote device is used for receiving the storage battery monitoring data sent by protocol conversion device 300 and uploading to power dispatching centralized control system, monitoring host 400 is used for displaying the storage battery monitoring data and carrying out limit alarm.
