| 1 | a |
| 2 | b |
| 3 | c |
Step 2012, the first terminal sends the first indication information to the target second terminal indicated by the identifier of the target second terminal.
assuming that the identifier of the target second terminal is a, the first terminal sends first indication information to the target second terminal indicated by the identifier a of the target second terminal. The first indication information may be used to indicate that the target substation enters a discharging state, and for example, the first indication information may include that the switches K2, K3, K5, and K6 are open, and K1, K4, and K7 are closed.
And step 202, the second terminal controls the first storage battery pack to enter a target operation state based on the first indication information.

and 203, the second terminal collects the circuit parameters of the circuit where the first storage battery pack is located in real time.
In order to monitor the charging state or the discharging state of the storage battery pack in real time, the second terminal can acquire the circuit parameters of the circuit where the first storage battery pack is located in real time. For example, the preset time period may be 30 minutes.
the circuit parameters may include, among others, voltage and current. For example, the voltage may include a voltage of the first battery pack, a voltage of the first battery cell, and a current of the first battery pack, wherein the first battery cell is any one of the first battery cell pack.
In the embodiment of the invention, the first terminal calculates the capacity of the current storage battery pack through the current in the circuit parameters sent by the second terminal, and when the capacity of the storage battery pack is smaller than the preset capacity value, the storage battery pack is generally considered to be unusable, and the storage battery pack is required to be replaced in time. Assuming that the maximum capacity of the storage battery pack is C and the current capacity of the storage battery pack is C1, if C1< C × q, the storage battery pack is considered to be about to be used any more, and the safety is low, so that the operation and maintenance personnel can determine that the storage battery pack cannot be used any more and should replace the storage battery pack in time. Wherein q is a constant and is greater than 0 and less than 1. In the embodiment of the present invention, q may be 70%, 50%, or 40%, which is not limited in the embodiment of the present invention.
alternatively, when the capacity of the current storage battery pack is calculated through the current in the circuit parameter, the capacity c1 of the current storage battery pack can be obtained by adopting a capacity calculation formulaWherein p is the sampling times of the first terminal in one hour according to the preset time length, and n is the sampling times of the first terminal in k (k)>0) And the Ii is the current value of the current storage battery pack obtained by sampling the ith time of the first terminal in k hours. For example, if the preset time period is 10 minutes, k is 2, p is 6, n is 12, the current capacity of the battery pack existsIf c1<C q, then the operation and maintenance personnel can determine that the first battery pack can no longer be used. Wherein q is a constant and is greater than 0 and less than 1.
In the embodiment of the present invention, k may also be 8.5, that is, k may be an integer or a decimal, which is not limited in the embodiment of the present invention.
and step 204, the second terminal sends the circuit parameters to the first terminal.
After the second terminal collects the circuit parameters, the collected circuit parameters are sent to the first terminal and stored by the first terminal, and the circuit parameters of a plurality of storage battery packs sent by a plurality of second terminals can be stored in the first terminal.
Step 205, when the first terminal receives the second monitoring instruction, detecting whether the voltage in the circuit parameter reaches a preset voltage value.
In the charging or discharging process of the first storage battery pack, the first terminal may detect whether the voltage in the circuit parameter reaches a preset voltage value when receiving the second monitoring instruction.
And step 206, when detecting that the voltage in the circuit parameters reaches the preset voltage value, the first terminal sends second indication information to the second terminal.
The second indication information is used for indicating the second terminal to control the first storage battery pack to exit the target operation state.
On the one hand, when the target operating state is a charging state, assuming that the first battery pack includes 110 first battery cells, the voltage of each first battery cell is 2V (volt), the voltage of the first battery pack is 220V, and when the voltage in the circuit parameter is the voltage of the first battery pack, the preset voltage value may be 253V; when the voltage in the circuit parameter is the voltage of the first battery cell, the preset voltage value may be 2.3V.
when the voltage in the circuit parameter is the voltage of the first storage battery pack, and when the first terminal detects that the voltage in the circuit parameter reaches 253V, the first terminal may send second indication information to the second terminal, where the second indication information is used to indicate the second terminal to control the first storage battery pack to exit the charging state, that is, to indicate the second terminal to control the first storage battery pack to stop charging.
when the voltage in the circuit parameter is the voltage of the first single storage battery, and when the first terminal detects that the voltage in the circuit parameter reaches 2.3V, the first terminal may send second indication information to the second terminal, where the second indication information is used to indicate the second terminal to control the first storage battery to exit from the charging state, that is, to indicate the second terminal to control the first storage battery to stop charging.
On the other hand, when the target operating state is the discharging state, assuming that the first battery pack includes 110 first battery cells, the voltage of each first battery cell is 2V, the voltage of the first battery pack is 220V, and when the voltage in the circuit parameter is the voltage of the first battery pack, the preset voltage value may be 198V; when the voltage in the circuit parameter is the voltage of the first battery cell, the preset voltage value may be 1.8V.
when the voltage in the circuit parameter is the voltage of the first storage battery pack, and when the first terminal detects that the voltage in the circuit parameter reaches 198V, the first terminal may send second indication information to the second terminal, where the second indication information is used to indicate the second terminal to control the first storage battery pack to exit the discharge state, that is, to indicate the second terminal to control the first storage battery pack to stop discharging.
when the voltage in the circuit parameter is the voltage of the first single storage battery, and when the first terminal detects that the voltage in the circuit parameter reaches 1.8V, the first terminal may send second indication information to the second terminal, where the second indication information is used to indicate the second terminal to control the first storage battery to exit the discharge state, that is, to indicate the second terminal to control the first storage battery to stop discharging.
in addition, the second terminal can also acquire the ambient temperature, and the ambient temperature is mainly used for converting the battery capacity and monitoring the running environment of the direct current system.
and step 207, the second terminal controls the first storage battery pack to exit the target running state based on the second indication information.
And when the second terminal receives second indication information sent by the first terminal, the second terminal controls the first storage battery pack to exit the target running state based on the second indication information. In the discharging process of the first storage battery pack, the voltage of the first storage battery pack is gradually increased, so that when the voltage of the first storage battery pack reaches a preset first voltage value, the first storage battery pack cannot be continuously charged and should be subjected to float charging from strong charging, that is, the first storage battery pack should be switched from a charging state to a normal working state, and under the condition, the second terminal controls the first storage battery pack to stop charging, so that the storage battery pack is prevented from being damaged.
When the first terminal detects that the voltage in the circuit parameter is smaller than the first voltage value and larger than the preset second voltage value, the first terminal may determine that the first storage battery pack can continue to be charged, and in this case, the first terminal does not send the second indication information to the second terminal.
The transformer substation storage battery monitoring method provided by the embodiment of the invention has higher operation reliability, and simultaneously has lower cost due to the utilization of the existing dispatching automation system resources. The monitoring and control functions of the existing dispatching automation system are expanded and applied to the charging and discharging test work of the storage battery of the transformer substation, and the application range, the application degree and the application level of the automation system are improved. The method changes the working method and the working process of the traditional charging and discharging test of the storage battery of the transformer substation, reduces the labor intensity of workers and saves the cost of manpower and material resources.
It should be noted that, the sequence of the steps of the transformer substation storage battery monitoring method provided in the embodiment of the present invention may be appropriately adjusted, and the steps may also be increased or decreased according to the circumstances, and any method that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the protection scope of the present invention, and therefore, no further description is given.
