Method for monitoring heavy oil diesel generator set

Abstract

The invention provides a method for monitoring a heavy oil diesel generator set. The method comprises the following steps: the detected parameters are divided into a key parameter group and a normal parameter group, each single chip computer reads the address of the single chip computer system through an I / O (Input / Output) interface, a high-speed collection plate and a normal collection plate are respectively defined according to the collection frequency corresponding to the read address; the high-speed collection plate collects the key parameter group of the set at high frequency and transmits the key parameter group to the normal collection plate; the normal collection plate circularly collects the normal parameter, collects the protection action situation, judges the parameter alarm, carries out simple filtering operation to the data, and combines data delivery protocol PC at different times at low frequency. According to the method for monitoring the heavy oil diesel generator set, the running parameters of the set are recorded, analyzed and displayed completely in real time, the influence on the working change of the set caused by the change of heavy oil viscosity is truly reflected, the initial complex hardware monitoring system is simplified, and the working load of the monitoring worker is reduced.

Description

technical field [0001] The invention belongs to the field of industrial measurement and control, and in particular relates to a monitoring method for a heavy oil diesel generating set. Background technique [0002] As a kind of electromechanical system, diesel generator set has very complicated working conditions. During the process of manufacture, operation and maintenance, many parameters need to be monitored in real time. These parameters include the speed of diesel engine, engine oil temperature, engine oil pressure, coolant temperature, and Including generator voltage, current, power, power factor, frequency. The situation of heavy oil diesel generator sets is more complicated. Because the heavy oil needs to be heated at a high temperature and the viscosity decreases before it can be supplied to the diesel engine for combustion. Insufficient heating will cause the viscosity of the heavy oil to be too high, and excessive heating will cause the viscosity of the heavy oil...

AI Technical Summary

Problems solved by technology

[0004] 1. When analyzing the operation of the unit, the average value over a period of time is used, which cannot truly reflect the change in the work of the unit when the viscosity of the heavy oil changes. Heavy Oil Viscosity Scheme Creates Huge Difficulties

[0005] 2. It is impossible to distinguish whether the fluctuation of the output power of the unit system is a theoretical normal fluctuation or an abnormal interference fluctuation

[0006] 3. The entire monitoring system is huge and complex, and the subsystems are independent of each other, making it difficult to ensure the synchronization and timely recording

[0007] 4. A large number of people are required to participate at the same time, and they are responsible for each subsystem separately, which consumes a lot of manpower

Therefore, the heavy oil diesel generator set requires more parameters to be collected and higher real-time requirements. It requires as many as hundreds of parameters within 1 second to be called a working point and have recording value. However, the existing technology can't do it yet
