Description

Technical Field

[0001] This invention relates to the field of steel production technology, and in particular to a control method for recording and early warning of incoming line voltage based on status word communication. Background Technology

[0002] The grid voltage fluctuations in the double high-voltage rolling mill are significant, frequently exceeding 10%, posing a substantial risk and hazard to the stable operation of electrical equipment. Current technology relies solely on a high-voltage control system for monitoring incoming voltage. Furthermore, the real-time curve and historical trend records from this system have long sampling cycles and low resolution, making it unable to accurately record short-term grid fluctuations or reflect them in historical trends. Additionally, the lack of data communication and sharing between the high-voltage control system and the rolling mill control system prevents intelligent early warning systems based on voltage fluctuations outside the normal range. Consequently, excessively high or fluctuating grid voltages can cause irreversible and severe damage to electrical equipment, ranging from a significant reduction in equipment lifespan to complete equipment failure and accidents.

[0003] The main defects and shortcomings of existing technologies are:

[0004] 1. The lack of an incoming line voltage monitoring system with a short sampling and scanning cycle and high resolution means that when the incoming line voltage is too high or fluctuates significantly, it cannot be identified by the waveform curve in a timely manner, thus making it impossible to perform corresponding fault analysis.

[0005] 2. The rolling line control system lacks a waveform curve control system for the incoming voltage and does not display the accurate incoming voltage in real time, which makes it impossible to perform intelligent early warning control for abnormal incoming voltage during normal production rolling process. Summary of the Invention

[0009] Based on the reference value of the incoming line voltage, the communication board performs one-to-one status word communication matching, transmits the incoming line voltage signal to the hierarchical channel at a fixed point, and writes parameters and selectively imports them through the combination of connectors and hierarchical channels.

[0010] The communication processing unit of the rolling control program receives voltage signal data that matches the connector, and compares the dynamic monitoring data with the actual measurement data through real-time voltage signal data monitoring.

[0011] The received voltage data signal is converted into data. The converted input voltage signal is processed, the dual-channel waveform of the input voltage signal is continuously recorded, and a voltage range warning is set.

[0012] As a further improvement of the present invention: the step of transmitting the detected voltage signal to the control board of the speed regulating device includes:

[0028] The data conversion formula is set so that when the rolling mill control program receives the voltage data signal collected by the sensor and transmitted by the communication cable, it will trigger the intelligent calculation program to intelligently convert the voltage data signal.

[0029] The data conversion formula is: U = Voltage data signal received from communication ÷ 16384 × Reference value of incoming line voltage, where U is the voltage value output after data conversion, and 16384 is the per-unit value corresponding to the reference value of 100% incoming line voltage.

[0030] As a further improvement of the present invention: the step of continuously recording the dual-channel waveform of the input voltage signal by processing the converted input voltage signal includes:

[0072] Detailed solution of the present invention:

[0073] Step 1: Identify and detect the incoming line voltage.

[0074] The incoming voltage of the drive cabinet is detected by a voltage transformer, and then the detected voltage signal is transmitted to the signal receiving terminal of the DC drive cabinet through a signal transmission cable.

[0093] Furthermore, the received voltage data signal refers to the voltage data signal received by the back zone control system and the rolling mill control system, which is collected by sensors and transmitted via communication cables; U = voltage data signal received from communication ÷ 16384 × reference reference value of the incoming line voltage is the calculation formula for data conversion. The control program performs intelligent conversion of the voltage data signal according to the above formula. U refers to the voltage value output after data conversion, and 16384 refers to the per-unit value of the reference reference value corresponding to 100% of the incoming line voltage.

[0094] Step 8: Design a signal recording and section early warning system.

[0095] By establishing variables, archiving, and importing the intelligently converted incoming voltage signal into a high-speed data acquisition terminal, continuous dual-channel intelligent waveform recording of the incoming voltage signal is achieved. Then, based on the fact that the voltage is not within 90%-110% of the rated voltage of the electrical equipment, intelligent interval early warning is designed to ensure that the equipment operates within the safe voltage range.

[0097] This invention can solve the problem that the lack of a short sampling period and high resolution incoming line voltage monitoring system leads to the inability to identify the waveform curve in a timely manner when the incoming line voltage is too high or fluctuates greatly. This invention enables rapid analysis of the corresponding voltage faults and improves fault handling efficiency.

[0098] This invention can solve the problem that the rolling line control system does not have a waveform curve control system for the incoming line voltage and a real-time accurate display of the incoming line voltage, which leads to the inability to perform intelligent early warning control for abnormal incoming line voltage during normal production rolling. This invention can achieve a breakthrough in the bottleneck technology of intelligent early warning for abnormal incoming line voltage.

[0099] This invention can solve the problem that there is no signal source for the incoming line voltage in the rolling mill control system, which makes it impossible to perform data processing and application based on the incoming line voltage signal source. This can enable the potential for abnormal incoming line voltage to be controlled in its early stages, thereby avoiding equipment accidents and improving equipment availability.

[0100] This invention can solve the problem of not being able to accurately quantize and convert the input voltage signal due to the lack of a quantization conversion formula based on the input voltage. It can then achieve interlocking optimization and visual early warning based on accurate output signals, thereby improving the production rolling operation rate and reducing the energy consumption cost per ton of steel.

[0101] This invention can solve the problems of not being able to achieve efficient and accurate data communication and obtain accurate incoming line voltage data signals due to the lack of a communication control system based on machine combination. It can avoid signal communication errors and malfunctions during the control process, thereby avoiding frequent production interruptions and significantly increasing output, and reducing the production cost per ton of steel.

[0102] In summary, after reading this invention document, those skilled in the art can make various other corresponding modifications to the technical solutions and concepts based on this invention without creative mental effort, and all of these modifications fall within the scope of protection of this invention.
