The present disclosure relates to hinged engineering machinery, a panoramic surround-view system and a calibration method thereof. The hinged engineering machinery comprises at least two hinged structure segments sequentially connected by means of a hinged frame, wherein the at least two hinged structure segments comprise a first hinged structure segment, the first hinged structure segment comprising a first vehicle body and a cab arranged on the first vehicle body. The panoramic surround-view system comprises: a plurality of photographing devices, mounted on the first hinged structure segment and configured to photograph the environment around the hinged engineering machinery; an image processing device, configured to receive images photographed by the plurality of photographing devices and splice the images into a surround-view image around the entire first hinged structure segment; and a human-computer interaction component, configured to display the surround-view image spliced by the image processing device.

Hinged engineering machinery, panoramic surround-view system and calibration method thereof

Provided are a load transfer method and system in thunder and lightning weather. The method includes: detecting lightning and predicting a position and time of a lightning strike to obtain a lightning prediction result; determining a transmission line possibly struck by lightning in a power grid according to the lightning prediction result; determining a load transfer scheme; and before the lightning occurs, transferring at least part of loads on the transmission line possibly struck by lightning according to the load transfer scheme.

Method and system for transferring a load in a thunder and lightning weather

A lightning prewarning-based method for active protection against a lightning strike on an important transmission channel includes collecting meteorological element data, and establishing a transmission line-specific lightning strike probability prewarning model; using a maximum probability of a lightning strike prewarning level as a lightning strike prewarning level; performing equivalence calculation on a large-scale regional power system, using a minimum sum of a power loss risk cost and a regulation cost as an optimized objective function, and establishing a power flow transfer optimization model; and comparing a sum of a regulation cost and load power loss risk cost caused after the tie line is disconnected if regulation is performed before a lightning strike, and a load power loss risk cost caused if regulation is not performed, and when the regulation cost is not greater than the load power loss risk cost, performing regulation before the lightning strike.
