Crane energy storage monitoring and scheduling system and scheduling method thereof

Abstract

The invention provides a crane energy storage monitoring and scheduling system and a scheduling method thereof. The crane energy storage monitoring and dispatching system comprises a crane, a power generation device, an energy storage device, a controller, a potentiometer, a monitoring module, a second relay or a first relay, and a clutch, the crane comprises a driving unit, a lifting appliance and a power supply device, the input end of the power generation device is connected with the driving unit; the controller controls the power supply device to be electrically connected with the energy storage device or the power grid; the energy storage device is provided with a battery management module; the battery management module sends first monitoring information to the controller; a rotatingshaft of the potentiometer is connected with a transmission shaft of the lifting appliance, the potentiometer sends position information to the controller, the monitoring module sends second monitoring information to the controller, and the controller controls the power generation device to charge the energy storage device through the second relay or the first relay and the electromagnetic clutch.The crane energy storage monitoring and scheduling system and the scheduling method thereof can realize effective and reliable energy management and control 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.
