Embodiment Construction

[0015] The invention provides a digital monitoring method for ground power supply. The monitoring method includes: a ground power supply fault combination method and a fault response delay time calculation method. When the ground power supply fails, the delay / anti-delay protection will be performed immediately, and the ground power supply will be cut off after the delay / anti-delay ends, effectively protecting the safety of the aircraft power supply system and electrical equipment.

[0016] The ground power fault combination method is used to divide the ground power fault into single fault and combined fault. Among them, there are three types of single faults: single voltage faults, single frequency faults, and single phase sequence faults; combined faults are two or more single faults that occur at the same time.

[0017] The fault response delay time calculation method, that is, the reservoir model, is used to calculate the final fault response delay time. The volume of the ...

Abstract

The invention belongs to the technical field of computer application and relates to a digital monitoring method for ground power supply. It is characterized in that the method includes the following steps: ground power failure is divided into single-voltage failure and single-frequency failure modes; setting a fault response time threshold, cutting off the ground power supply when the fault response time reaches the threshold, and calculating the response time according to the following formula: Among them: h represents the continuous variation of voltage or frequency, and S represents the response time of the fault point. The invention provides a digital monitoring method for the ground power supply, which is used for real-time monitoring of the quality of the ground power supply connected to the aircraft, and immediately handles when the ground power supply fails and the power supply index fails to meet the requirements of the aircraft.

Description

technical field [0001] The invention belongs to the technical field of computer application and relates to a digital monitoring method for ground power supply. Background technique [0002] The aircraft ground power supply is mainly used for starting and electrifying the aircraft on the ground, etc., and the AC power system is mostly used to provide three-phase AC power for the aircraft in the landing state. When the ground power supply supplies power to the aircraft, different aircraft and different working conditions may cause instantaneous changes in the power supply parameters of the ground power supply. Delay protection, cut off the ground power supply after the delay / anti-delay is over, so as to ensure the safety of the aircraft power supply system and electrical equipment. In the prior art, there is no effective method for fault detection and control of aircraft ground power supply. Contents of the invention [0003] The technical problem solved by the present inv...
