Description
Technical Field
[0001] The present invention relates to the technical field of electric blowers, and more particularly to a simulation start-up system for electric blowers. Background Art
[0002] The function of the electric blower is to supply air to the blast furnace to ensure the oxygen required for the burning coke and the injected fuel in the blast furnace, and to provide the gas power required to overcome the resistance of the blast furnace column. The blowers used in modern large and medium-sized blast furnaces are mostly centrifugal blowers and axial flow blowers driven by steam turbines. In recent years, large-capacity synchronous electric blowers have been used. Although this type of blower consumes a lot of electricity, it is easy to start, easy to maintain, and requires less investment.
[0003] The existing electric blower system includes an electric blower, an operating cabinet for driving the electric blower, a 1G high-voltage power supply cabinet, a high-voltage PT cabinet, a 3G main motor operating cabinet, a 5G high-voltage starting cabinet, an 8G high-voltage supply cabinet, a reactive cabinet one and a reactive cabinet two.
[0004] For electric blowers, existing electric blowers often perform simulated start-up before officially starting up. However, existing means can only simply check the correctness of the start-up sequence and start-up steps of the control loop channel, and cannot completely test whether the start-up and action channels of the protection device are normal, thereby being unable to guarantee safety issues during normal start-up. If the protection device is abnormal, it may cause safety accidents or damage to the electric blower system. Summary of the invention
[0005] The technical problem to be solved by the present invention is to provide a simulation starting system for an electric blower in view of the deficiencies in the prior art, so as to solve the technical problem that the prior art electric blower cannot be fully inspected.
[0006] The present invention provides a simulated start-up system for an electric blower, the system comprising:

[0012] The process feedback module is used to feed back the execution result of the electric blower system after executing the control instruction.
[0013] As a further improvement, the function processing module is used to set real-time instructions and build a log based on the feedback of the execution results.
[0014] Further, when the first operating result is inconsistent with the second operating result, the protection device of the electric blower system operates abnormally; when the first operating result is consistent with the second operating result, the electric blower system operates normally.
[0015] According to the startup and action channels of the electric blower system, an electrical protection channel, a process protection channel and an accident protection channel are established in the simulated operation environment. When the simulated operation module is started, multiple digital simulation operations are performed on each protection channel.
[0016] Furthermore, after each protection channel performs digital simulation operation, it waits for a set time interval before performing the next digital simulation operation.
[0017] Furthermore, when the simulation operation module is started, the detection method for the electrical protection channel is: according to the simulation instruction, the action of the emergency stop switch of the operation box next to the electric blower of the electric blower system in the simulation operation environment is simulated, and the signal of the circuit breaker of the operation cabinet of the electric blower system in the simulation operation environment is used as the first operation result;
[0018] collecting an action signal of a circuit breaker of an operating cabinet in the electric blower system after the execution control module sends a control instruction to the electric blower system, and using the action signal as a second operation result;
[0019] When the first operation result is consistent with the second operation result, the electrical protection channel is normal.
[0020] Furthermore, when the simulation operation module is started, the detection method for the process protection channel is: according to the simulation instruction, the action of the emergency stop switch of the operation box next to the electric blower of the electric blower system in the simulation operation environment is simulated, and the signal of the circuit breaker of the operation cabinet of the electric blower system in the simulation operation environment is used as the first operation result;
[0021] collecting an action signal of a circuit breaker of an operating cabinet in the electric blower system after the execution control module sends a control instruction to the electric blower system, and using the action signal as a second operation result;
[0022] When the first operation result is consistent with the second operation result, the process protection channel is normal.
[0023] Furthermore, when the simulation operation module is started, the detection method for the accident protection channel is: according to the simulation instruction, the action of the manual stop switch of the electric blower detection system of the electric blower system in the simulated operation environment is simulated, and the signal of the circuit breaker of the operation cabinet of the electric blower system in the simulated operation environment is used as the first operation result;
[0024] collecting an action signal of a circuit breaker of an operating cabinet in the electric blower system after the execution control module sends a control instruction to the electric blower system, and using the action signal as a second operation result;
[0025] When the first operation result is consistent with the second operation result, the accident protection channel is normal.
[0026] Furthermore, the time interval is 5 minutes.

At the same time, each module executes control instructions and corresponds to the feedback data of each electric blower system component, so that unified control can be achieved through the data center, and the corresponding control instructions and control logic can be automatically matched through the data feedback from the electric blower system components to achieve automatic control.
[0043] The electric blower system connected to this system includes an electric blower, an operating cabinet for driving the electric blower, a 1G high-voltage power supply cabinet, a high-voltage PT cabinet, a 3G main motor operating cabinet, a 5G high-voltage starting cabinet, an 8G high-voltage supply cabinet, a reactive cabinet one and a reactive cabinet two.
[0044] Before specific implementation, the status of each electric blower system is checked through the status identification setting module to ensure that each electric blower system is in a normal state and can obtain feedback data.
[0045] The information of the three protection channels is collected through the component integrated input module; digital simulation operation is performed according to the preset real-time instructions to obtain the first operation result; digital simulation operation is performed according to the control instructions to obtain the second operation result. After the simulation startup is completed, it is judged whether the protection channel is operating normally based on the first operation result and the second operation result.
[0046] The three protection channels are electrical protection channel, process protection channel and accident protection channel.

After the execution control module sends the control instruction to the electric blower system, the action signal of the operating cabinet circuit breaker in the electric blower system is collected, and the action signal is used as the second operation result. When the first operation result is consistent with the second operation result, when the second operation result is that the operating cabinet circuit breaker quickly and accurately triggers the electrical protection trip, the electrical protection channel is confirmed to be successful.

When the second operation result is that the operating cabinet circuit breaker that drives the electric blower is triggered to trip, the purpose of process emergency stop protection is achieved.
[0054] Wait for another 5 minutes and repeat the simulation start-up. According to the simulation instructions, the action of the manual stop switch of the electric blower detection system of the electric blower system in the operating environment and the action of the accident shutdown protection pressure plate of the operating cabinet are simulated to simulate the signal of the operating cabinet circuit breaker of the electric blower system in the operating environment as the first operation result. After the execution control module sends the control instruction to the electric blower system, the action signal of the operating cabinet circuit breaker in the electric blower system is collected and the action signal is used as the second operation result.
