Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The operation control method provided by the application can be applied to the application environment shown in fig. 1. The control device 101 in the plant 100 communicates with a relay protection device 200, which is used for relay protection of devices in the plant. The unit 100 may be a diesel generator set, or a renewable energy conversion generator set, such as a pumped storage unit; the unit can be a small-sized unit, and can also be but not limited to a small-sized generating set, a medium-sized generating set, a large-sized generating set and the like. The control device 101 may be implemented by, but not limited to, an independent server or a server cluster composed of a plurality of servers.
In one embodiment, as shown in fig. 2, an operation control method is provided, which is described by taking an example of the method applied to the control apparatus in fig. 1, and includes:
s101, determining a target working condition mode to be operated by the unit according to a preset unit operation flow.
The unit may be a diesel generator set, or may be a renewable energy conversion generator set, such as a pumped storage unit, and the type of the unit is not limited herein. The unit can operate in different working condition modes, and the working states and the electrical parameter characteristics of all devices in the unit can be different under different working condition modes. For example, the operating mode for the pumped storage unit can comprise various operating modes such as no-load power generation, phase modulation of power generation, pumping, dragging, black start and the like.
The control device may determine a target working condition mode to be operated by the unit according to the unit operation flow, for example, working condition modes to be sequentially operated may be set according to a time sequence in the unit operation flow, and the control device may determine the target working condition mode to be operated according to the current time; or the control equipment can acquire a user input instruction to determine a target working condition mode to be operated; the manner of obtaining the target operating mode is not limited herein.
And S102, sending the target working condition mode to the relay protection device based on the communication connection between the unit and the relay protection device.
The control device may transmit the target operating mode to the relay protection apparatus. The relay protection device is used for carrying out relay protection on equipment in the unit. For example, for a pumped storage unit, the relay protection device can perform low-voltage protection on generator equipment in the unit, and the like.
The unit may be in communication connection with the relay protection device, and the communication connection may be a wired connection or a wireless connection, which is not limited herein. Specifically, the communication connection may be implemented by data transmission in a field bus communication manner, and the control device and the relay protection device in the unit may be connected by a bus communication cable. The field bus communication mode can be an industrial data bus and can be a bottom layer data communication network. The field bus communication mode may be, but not limited to, CANopen bus, ethernet bus, etc.
S103, receiving feedback information from the relay protection device, and controlling the unit to operate according to the feedback information; the feedback information is used for representing that the relay protection device works in a target relay protection mode, and the target relay protection mode is determined by the relay protection device based on the target working condition mode.
After the relay protection device receives the target working condition mode through the communication connection, the target relay protection mode corresponding to the target working condition mode to be operated by the unit can be determined according to the corresponding relation between the target working condition mode and the relay protection mode. The relay protection mode is a mode that the relay protection device performs relay protection on equipment in the unit, and the relay protection device can correspond to different relay protection modes in different working condition modes and can also correspond to the same relay protection mode in different working condition modes. Under the condition that the relay protection device operates in the target relay protection mode, relay protection can be performed on one device in the unit, relay protection can also be performed on a plurality of devices in the unit, and the relay protection device is not limited herein; the devices to be protected corresponding to different relay protection modes can be the same or different.
For example, when the pumped storage unit operates in a power generation condition, the relay protection device may enter a first relay protection mode, turn off low-voltage protection and low-power protection for the generator, and turn on reverse power protection; when the pumped storage unit operates in a pumping working condition, the relay protection device can enter a second relay protection mode to close reverse power protection on the generator and open low-voltage protection and low-power protection.
After the relay protection device determines the target relay protection mode based on the target working condition mode, feedback information can be generated and used for informing the unit of the readiness of the relay protection device, so that the control equipment can control the unit to operate according to the feedback information. The feedback information can be used for representing that the relay protection device works in a target relay protection mode, and after the control equipment in the unit receives the feedback information, the relay protection device can be determined to be normally set, and the unit is controlled to operate in the target working condition mode. When the control equipment in the unit does not receive the feedback information, the unit can consider that the relay protection device cannot effectively protect the unit in real time, and the unit can be controlled to trip and stop.
Because the target working condition mode and the feedback information sent between the relay protection device and the unit are sent through the communication connection between the unit and the relay protection device, cables can be prevented from being respectively laid aiming at the target working condition mode and the feedback information, the workload of cable laying and wiring is reduced, and the operation reliability of the unit is improved.
And after the relay protection device enters the target relay protection mode, keeping the target relay keeping mode until a new target working condition mode is received, and determining the new target relay protection mode according to the new target working condition mode.
According to the operation control method, the target working condition mode of the unit to be operated is determined by the equipment according to the preset unit operation flow; then, based on the communication connection between the unit and the relay protection device, sending a target working condition mode to the relay protection device; finally, receiving feedback information from the relay protection device, and controlling the unit to operate according to the feedback information; the feedback information is used for representing that the relay protection device works in a target relay protection mode, and the target relay protection mode is determined by the relay protection device based on a target working condition mode. The unit and the relay protection device are in communication connection, and the target working condition mode is sent to the relay protection device through the communication connection, so that the relay protection device can obtain the target working condition mode based on the communication connection to determine the target working condition mode to be operated by the unit, and the target working condition mode determination error caused by unstable hard-wired connection is avoided; in addition, the relay protection device can keep a corresponding target relay protection mode based on the received target working condition mode, and the relay protection mode is prevented from being continuously changed and cannot be kept due to abnormal change of a switch position signal; by the method, the relay protection device can determine the corresponding target relay protection mode according to the correct target working condition mode, maintain the target relay protection mode, perform corresponding relay protection on equipment in the unit under the target working condition mode, avoid protection failure or protection misoperation and improve the operation reliability of the unit.
Fig. 3 is a schematic flowchart of an operation control method in an embodiment, where the embodiment relates to a manner of controlling a device to issue a target operating mode, and on the basis of the embodiment, as shown in fig. 4, the step S102 includes:
s201, obtaining a communication connection state between the unit and the relay protection device.
Specifically, the control device can monitor the communication connection state between the unit and the relay protection device in real time. The communication connection state may include a normal communication connection state and an abnormal communication connection state. The control device may detect the communication connection state by sending a heartbeat signal or the like, and obtain the communication connection state.
S202, if the communication connection state is normal, sending a target working condition mode to a relay protection device so that the relay protection device keeps the target working condition mode until receiving the next target working condition mode.
If the communication connection state is normal, the control equipment can send the target working condition mode to the relay protection device through the communication connection under the condition that the control equipment determines the target working condition mode, so that the relay protection device keeps the target working condition mode until the next target working condition mode is received.
Further, if the communication connection state is abnormal, the control device may determine an operation control strategy of the unit according to the operation state of the unit.
The running state of the unit can be a state before starting, a state during starting and a stable working state. The control device may determine the operation state of the unit according to the operation information of the unit during operation, and may also determine the operation state of the unit according to a starting process of the unit, which is not limited herein.
For example, the control of a plurality of switches is required to be completed when the unit is started; for the pumped storage unit, the switch can be a phase-change isolating switch, can also be a pumped phase-modulation starting isolating switch, and can also comprise a back-to-back dragging isolating switch and the like, and the unit can operate in different working condition modes by controlling the position state of each switch. When the operation information shows that the control on the switches is not executed, the unit can be determined to be in a state before starting; when the operation information shows that the control of the switch A is executed and the control of the switch B and the switch C is not executed, the unit can be determined to be in a starting state; when the operation information shows that the control of all the switches is finished, the unit can be determined to be in a stable operation state. And if the unit is in the state before starting, continuing to execute the unit starting process.
When the communication connection state is abnormal, the unit cannot timely send the target working condition mode to the relay protection device after the working condition mode is switched, and the running risk of the unit is caused. Therefore, the control device can designate a response operation control strategy according to the operation state of the unit so as to ensure the safety of the unit and avoid protection refusal and protection misoperation of the relay protection device.
The operation control strategy in each operation state will be described in the following embodiments for different operation states.
In one implementation, if the operation state of the unit is the state before starting, the unit is set to be in the starting prohibition state.
Under the condition that the communication connection state is abnormal before the unit is started, the control equipment can set the unit to be in a starting prohibition state because the unit cannot send the target working condition mode to the relay protection device, so that the unit cannot be started normally.
In one implementation mode, if the running state of the unit is a starting state, the unit starting process is terminated, and a tripping instruction is sent to the relay protection device through the hard-wired connection between the unit and the relay protection device; and the tripping instruction is used for informing the relay protection device unit of being in a tripping state.
When the communication connection state is abnormal in the starting of the unit, part of equipment in the unit may already be in the working state, but the relay protection device cannot receive the target working condition mode due to the abnormal communication connection state, so the control equipment may send a trip instruction to the relay protection device through the hard-wired connection between the unit and the relay protection device. In particular, the control device may trigger a trip of the crew after a delay of a preset duration.
In one implementation mode, if the operation state of the unit is a stable operation state, the current operation working condition mode of the unit is maintained, the relay protection device is controlled to maintain the current operation relay protection mode, and the unit operation flow is prohibited from entering a working condition conversion flow or a normal shutdown flow.
And if the running state of the unit is a stable working state and a unit shutdown instruction is received, starting a trip flow of the unit, and sending a trip instruction to the relay protection device through the hard wiring connection between the unit and the relay protection device, wherein the trip instruction is used for informing the relay protection device that the unit is in a trip state.
Specifically, in order to avoid missending information to the relay protection device when the communication connection is abnormal, the control device can lock the normal shutdown and working condition switching button of the unit, and the unit is prevented from being stopped to switch the working condition mode.
According to the operation control method, the control equipment monitors the communication connection state between the unit and the relay protection device, and can adopt corresponding operation control strategies to the abnormal state of the communication state in different operation states of the starting operation of the unit, so that the unit operation risk caused by misjudgment of the relay protection device on the working condition mode of the unit due to the abnormal communication is avoided, the reliability of the relay protection operation can be effectively improved, and the operation reliability of the unit is improved.
