Detailed Description
Embodiments of the present disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present disclosure and are not to be construed as limiting the present disclosure.
The power supply method, apparatus, computer device and storage medium of the energy storage power station of the embodiments of the present disclosure are described below with reference to the accompanying drawings.
It should be noted that, the implementation body of the power supply method of the energy storage power station in the embodiment of the disclosure is a power supply device of the energy storage power station, and the device may be implemented by software and/or hardware, and the device may be configured in any electronic device. In the context of the present disclosure, the power supply method of the energy storage power station set forth in the embodiments of the present disclosure will be described below with "power supply device of the energy storage power station" as an execution subject, which is not limited herein.
Fig. 1 is a flow chart of a power supply method of an energy storage power station according to an embodiment of the disclosure.
As shown in fig. 1, the power supply method of the energy storage power station may include the steps of:
step 101, acquiring an operation state of the power system.
Specifically, an electric power quality monitoring instrument, such as an electric power quality analyzer or a digital oscilloscope, can be pre-installed, and is used for monitoring parameters of voltage, current, power factor and the like of the electric power system in real time and recording the parameters.
It should be noted that, through the running state of the power system, it can be judged whether the power system can perform stable and stable power supply for the load equipment currently. For example, if the power system is in a failure state, the power required by the load may not be provided, and the load loses the power supply of the power system.
And step 102, in response to the running state meeting a preset condition, controlling the battery pack to discharge so as to output the electric energy stored by the battery pack to the generator set.
The preset condition may be a black start condition.
As one possible implementation, the battery pack is controlled to discharge if the operating state is a power outage or power outage in response to determining that the operating state is a power outage.
In particular, the battery pack may be controlled to charge or discharge by an energy storage controller. Wherein the energy storage controller is from an energy storage system. The energy storage system comprises a battery pack and an energy storage controller. Wherein, the group battery is used for storing electric energy.
The generator set is used for providing power for a load.
It should be noted that, in order to ensure the integrated design of the energy storage system and the power system, the black start requirement is fully considered. The energy storage system needs to be connected with a control system, protection equipment, switching equipment and the like of the power system, and smooth transmission of signals and data is ensured.
In addition, when the energy storage system is selected, energy storage technology suitable for the energy storage power station can be selected, such as lithium ion batteries, sodium-sulfur batteries, compressed air energy storage and the like. And selecting an energy storage system with higher power and capacity according to the requirements of the power station and the expected black start performance.
The black start refers to that the energy storage system can quickly start and stably supply power so as to meet the starting and running requirements of the power system.
In addition, the control system and the protection device of the energy storage system need to be well integrated with the control system and the protection device of the power system. This includes ensuring that the transfer of signals and data is clear, enabling the energy storage system to accurately sense the state of the power system and respond accordingly, e.g., start the energy storage system, disconnect the load, etc.
The energy storage system should communicate with a monitoring system of the power system and be capable of communicating state and performance information of the energy storage system. This helps the power system operator monitor and evaluate the operation of the energy storage system and make necessary adjustments and decisions. After the energy storage power station is built, sufficient tests and verification should be performed to ensure the reliability and performance of the black start system. This includes simulating a black start process in the event of a power loss and checking the response and operation of the energy storage system.
In a normal operating state, it is necessary to ensure that the energy storage system is in a ready state, which includes management of a charging state, temperature control, monitoring of capacity, and the like, so as to ensure that the energy storage system can provide required electric energy at any time.
Step 103, starting a generator set to supply power for an operation load of the power system.
The operating load may be a consumer supplied by the power system.
Wherein the generator set may be used to power a load.
And 104, evaluating a control system of the power system to determine an evaluation result corresponding to the control system.
It should be noted that, in the case where the energy storage system supplies power, it is necessary to gradually restore the control system of the power system.
First, it is necessary to evaluate the failure or interruption of the control system, determine the cause and scope of the failure of the control system, and understand the specific scope of influence of the failure is critical for recovering the control system.
Specifically, data and audit logs may be collected first: the control system is analyzed for pre-fault, during-fault and post-fault data, logs, configuration files, and the like, and compared with the data under normal conditions to quickly determine the extent and impact of the fault. Performing field inspection: hardware facilities such as various devices, sensors, wiring boards, plug interfaces and the like are checked to see whether damage or abnormal conditions exist. While also checking for errors or other problems with the various software programs, communication protocols and algorithms in the control system. And (3) performing functional test: simulation operations and experimental tests are performed to confirm whether the fault source is from the control system or from external factors. For example, if the fault source is an error from the input value, we can inject some interference signals from outside to observe whether the system reaction is inconsistent or abnormal. The evaluation result contains the reason and the range which lead to the failure of the control system.
And 105, determining each device to be monitored according to the evaluation result.
Optionally, in the case that the evaluation result is that the power interruption causes the control failure, it is determined that each device to be monitored at least includes a power line, a circuit breaker and a power distribution device.
And under the condition that the evaluation result is that the device fault causes the control failure, determining that each device to be monitored at least comprises a cable, a connector, a sensor, an actuator and a control device.
It should be noted that, according to the result of the evaluation, troubleshooting may be performed to find out a specific problem that causes the failure of the control system. This may include checking the status of the cable, connector, sensor, actuator or control device, and troubleshooting possible points of failure.
If the control system failure is due to a power interruption, the power supply needs to be restored. The power supply lines, circuit breakers and distribution equipment are checked to ensure that the power supply is restored to normal.
And 106, determining the states of the devices, and repairing the target device in the fault state.
It should be noted that, after each device to be monitored is determined, it may be determined whether the state of each device is a fault state, and then the device in the fault state is repaired.
Wherein the target device may be a device in a failure state.
It should be noted that if the control system involves data recording or storage, such as historical data, configuration files, or parameter settings, etc., lost or corrupted data needs to be recovered. This may involve recovering data from the backup or performing a data recovery operation.
In the embodiment of the disclosure, firstly, an operation state of a power system is obtained, a battery pack is controlled to discharge in response to the operation state meeting a preset condition, electric energy stored by the battery pack is output to a generator set, the generator set is started to supply power to an operation load of the power system, a control system of the power system is evaluated to determine an evaluation result corresponding to the control system, each device to be monitored is determined according to the evaluation result, the state of each device is determined, and a target device in a fault state is repaired. Therefore, the energy storage power station can be started in a short time, stable electric power support is provided for the power grid, the system adopts the battery pack to store energy, and the system has the advantages of environmental protection, high efficiency, low cost and the like, is simple in structure and easy to realize, has wide application prospect, and has the characteristics of quick start, high energy density, flexibility, sustainability and the like, so as to cope with emergency situations of the power system and provide continuous electric power supply.
Fig. 2 is a flow chart of a power supply method of an energy storage power station according to an embodiment of the disclosure.
As shown in fig. 2, the power supply method of the energy storage power station may include the steps of:
step 201, the voltage and frequency of the power system are monitored.
Specifically, the electric energy quality monitor can be used for detecting and recording parameters such as voltage, current, frequency, power factor and the like of the power grid port in real time, and meanwhile, the electric energy quality problems such as waveform distortion, harmonic waves and the like can be recorded, so that the subsequent analysis and processing are facilitated.
Specifically, the frequency of the power system can be monitored singly or in a linkage manner based on the frequency meter, and an abnormal alarm signal is sent to remind a manager to process.
Alternatively, a digital oscilloscope may be used to display a waveform image of a voltage, current, or another signal over time, as well as information about frequency, period, etc.
Step 202, in the case that the voltage and/or frequency is abnormal, controlling the battery pack to discharge.
When the voltage and frequency of the power system are abnormal, there are generally the following cases:
abnormal voltage: such anomalies are manifested as voltages above or below the normal voltage range, which may lead to equipment damage, equipment overheating, or downtime. For example, when the voltage drops below the nominal value, both the device current and its temperature rise; conversely, when the voltage rises above the nominal value, it also causes overload of the equipment and possible damage.
Frequency anomaly: such anomalies are manifested as grid frequencies above or below the normal frequency range, possibly leading to electrical equipment failure. For example, as the frequency decreases, both motor drive and torque may decrease, which may lead to potential damage to the motor; conversely, when the frequency increases, the device may suffer from unstable performance and overheating.
Therefore, the discharging of the battery pack can be controlled under the condition that the voltage and/or the frequency are abnormal, and the condition that the power system is bad, the power system is invalid and cannot supply power stably is indicated, so that black start is needed, namely, the energy storage system is started, the load is disconnected, and the battery pack is used for supplying power to the load.
Starting an energy storage system: and starting the energy storage system according to the indication of the black start plan. This may involve switching the energy storage system from a standby mode to an operational mode, outputting stored electrical energy to the generator set, starting the generator set to begin providing power to the power system.
Step 203, starting the generator set to supply power for an operation load of the power system.
And 204, evaluating a control system of the power system to determine an evaluation result corresponding to the control system.
And step 205, determining each device to be monitored according to the evaluation result.
And 206, determining the states of the devices, and repairing the target device in the fault state.
It should be noted that, the specific implementation manner of the steps 203 to 206 may refer to the above embodiments, and will not be described herein.
In response to determining that the power system resumes operation, the load will be reconnected step by step based on the power system, step 207.
It should be noted that, when the power system is restored to the normal operation state, the load device may be gradually reconnected. Sufficient testing and verification is required to ensure that the energy storage system is able to properly supply the load before reconnecting the load. Once all load devices are successfully connected and operating properly, the energy storage plant should be in a steady state. Further monitoring and adjustment are performed to ensure that the system is restored to a normal operating state. In the design and construction process, the performance, reliability and safety of the energy storage system should be fully considered, and necessary tests and verification should be performed.
In summary, the control system of the power system can be gradually recovered under the condition that the energy storage system provides power, so that the monitoring, protecting and automatic control functions of the power system are realized
In order to achieve the above embodiments, the present disclosure further proposes a power supply device of an energy storage power station.
