Crane Energy Storage Monitoring and Scheduling System and Its Scheduling Method

Abstract

The invention provides a crane energy storage monitoring and dispatching system and a dispatching method thereof. The crane energy storage monitoring and dispatching system includes a crane, a power generation device, an energy storage device, a controller, a potentiometer, a monitoring module, and a second relay or a first relay and a clutch , the crane includes a drive unit, a spreader and a power supply unit, the input end of the power generation unit is connected to the drive unit, the controller controls the power supply unit to be electrically connected to the energy storage device or the grid, the energy storage device has a battery management module, and the battery management module provides the controller Send the first monitoring information, the rotating shaft of the potentiometer is connected with the transmission shaft of the spreader, the potentiometer sends the position information to the controller, the monitoring module sends the second monitoring information to the controller, the controller communicates with the electromagnetic through the second relay or the first relay The clutch controls the power generation device to charge the energy storage device, and the scheduling method of the above system. Both the crane energy storage monitoring and scheduling system and its scheduling method can effectively and reliably control the energy of the system.

Description

technical field [0001] The invention relates to the technical field of hoisting machinery, in particular to a crane energy storage monitoring and dispatching system and a dispatching method of the crane energy storage monitoring and dispatching system. Background technique [0002] As an assembly point and hub of water and land transportation, a port is a distribution center for industrial and agricultural products and foreign trade export materials, as well as a place for cargo loading and unloading and ship berthing. Among them, the loading and unloading of goods is operated by port cranes. The lifting height of port cranes is generally between 20 meters and 40 meters, and the rated lifting weight is between 30 tons and 40 tons. The average power consumption of port cranes is 50 kW to 60 kW per hour, and the monthly power consumption is about 40,000 degrees. It can be seen that the power consumption of port cranes is astonishing. [0003] Therefore, in order to save energ...

AI Technical Summary

Problems solved by technology

[0004] First, the power generation device is connected to the drive unit after the port crane starts lowering the spreader, which causes a lag in the power generation of the power generation device and affects the power generation;

[0005] Second, the lifting speed of the container by the spreader needs to be manually controlled, which requires high technical requirements for the port crane operator;

[0006] Third, before the energy storage device performs charging and discharging operations, there is a lack of state monitoring of the energy storage device, resulting in certain potential safety hazards;

[0007] Fourth, there is a lack of real-time monitoring of key factors such as grid voltage, frequency, and phase. As a result, when the grid or converter fails, the power supply cannot be switched in time, resulting in poor reliability and low safety.
