Ocean platform crude oil generator set oil head working state monitoring method

Abstract

The invention discloses a method for monitoring the working state of an oil head of an ocean platform crude oil generator set. The method comprises the following steps of: acquiring instantaneous rotating speed, torsional vibration and thermal parameters of the crude oil generator set on line by using an FPGA (Field Programmable Gate Array) acquisition and network communication method; the fault state of each crude oil generator set is preliminarily monitored and diagnosed through fusion monitoring of instantaneous rotating speed, torsional vibration and thermal parameters, a preliminary diagnosis result is obtained, and an alarm level is given; and according to the preliminary diagnosis result, a manager is prompted to perform off-line indicator diagram data acquisition on a fault cylinder of the crude oil generator set on site, and the fault type is further accurately determined through an indicator diagram monitoring analysis method. The invention provides a method for monitoring the working state of the oil head of the crude oil generator set of the ocean platform, which is used for predicting the occurrence of a series of faults caused by unbalanced operation such as reduced power capability or cylinder limp due to the oil head, and providing condition-based maintenance decisions for cabin management personnel.

Description

technical field [0001] The invention belongs to the field of generating sets, and in particular relates to a method for monitoring the working state of an oil head of an offshore platform crude oil generating set. Background technique [0002] At present, the power and electricity supply of the offshore drilling platform comes from the crude oil generator set of the drilling platform. The existing crude oil generator set of the drilling platform usually consists of 5 generator sets, shouldering the heavy burden of supplying power for the entire power system on the platform, known as the production The heart of the work platform. Due to the compact design and functional positioning of the entire offshore drilling platform structure, the crude oil generator set on the drilling platform obtains fuel in the following way: the oil drilled from the seabed is transported to the FPSO for preliminary treatment before being transported to the crude oil on the drilling platform genera...

AI Technical Summary

Problems solved by technology

Therefore, the fuel quality of the crude oil generating set is poor, resulting in abnormal oil head of the injector, resulting in insufficient combustion, uneven work, and even misfire

Insufficient combustion and uneven work will reduce the working ability of the offshore drilling platform; fire will cause unbalanced operation such as lame cylinders, which will cause a series of failures; affect the normal work of the crude oil generator fuel system, and greatly affect the maintenance of crude oil generators. Management creates uncertainty and inconvenience

Once there is a problem with the crude oil generator set on the platform, the working efficiency of the platform's power system will be reduced, and even paralyzed in severe cases, forcing the platform's oil drilling operation to be suspended and undergoing maintenance, resulting in huge energy and economic losses, which is not conducive to the realization of marine Efficient Mining in Exploration
