Embodiment Construction

[0022] A fault detection method in parallel operation of two sets, the specific steps are:

[0023] The first step is to build a fault detection system for parallel operation of two units

[0024] Fault detection system for parallel operation of two units, including: power acquisition module 1, speed acquisition module 2, voltage acquisition module 3, fault detection module 4, fault processing module 5; power acquisition module 1 is used to collect power parameters, and speed acquisition module 2 is used The parameters of the acquisition speed and the voltage acquisition module 3 are used to acquire the parameters of the voltage. The three modules are respectively connected to the fault detection module 4 with wires. The fault detection module 4 is used to detect whether there is a faulty unit and locate the faulty unit. The fault detection module 4 and The fault processing module 5 is connected by wires, and the fault processing module 5 is used to execute the processing sign...

Abstract

The invention discloses a parallel running fault detection method for double machine sets. The parallel running fault detection method for double machine sets includes that building a parallel running fault detection system for double machine sets, enabling a power gathering module (1), a rotating speed gathering module (2) and a voltage gathering module (3) to respectively gather power, rotating speeds and voltage parameters, sending to a fault detection module (4) through a lead, enabling the fault detection module (4) to detect whether there is a faulted machine set according to the parameters and locate the faulted machine set, and sending signals to a fault processing module (5) to execute faulted machine set processing signals. The parallel running fault detection method for double machine sets precisely detects the fault and meets quick and precise faulted machine set judging requirements in the parallel running of double machine sets.

Description

technical field [0001] The invention relates to a method for detecting a fault in the operation of a diesel generator set, in particular to a method for detecting a fault in the parallel operation of two sets. Background technique [0002] The power supply system is an important factor affecting the combat effectiveness of weapons and equipment. In order to improve the task reliability of the power supply system, the power supply mode of two diesel generator sets in parallel for redundant power supply is adopted for important weapons and equipment. This power supply method is based on the parallel connection of two diesel generator sets. If one of the sets fails, the fault detection system for parallel operation of the two sets will immediately cut off the power supply of the faulty set. The system has a set of fault detection methods. According to the original traditional detection method, it is mainly based on the principle that the reverse power unit is the faulty unit. ...
