Through the laws of physics and application of a mathematical model of fluid mechanics, VIVIUNAM calculated when an irregularity occurs on the premises.
It is common for distribution networks for water, gas or oil leaks in tanks storage, pumping failures or illegal connections exist. In order to avoid economic losses due to these causes, Dr. Cristina Green Rodarte , researcher at the Institute of Engineering, UNAM, designed a virtual guard who immediately detects anomalies in any kind of product .
The software called VIVIUNAM performs real-time logical deductions , allowing you to identify the type of failure and get to the root of the problem and thereby prevents loss of time, digging or manually search for the problem along the entire pipeline, said the researcher, who is also member of the Academy of Engineering.
The virtual vigilante works with an algorithm, which by the laws of physics and application of a mathematical model of fluid mechanics, calculates a series of data indicating what the behavior of gas pipelines, water or oil under normal operating conditions. These, in turn, are compared with the registration of pressure measurements that generates the pipe itself and the difference between them symptoms of the presence of leakage is obtained.
When the results of the mathematical model do not match the measurements recorded automatically, is because there is an error or abnormal event, and from that scenarios are sought; for example, that the pressure sensor is disconnected, there is a leak, making illegal or generally there is a disturbance that alters the behavior of fluids pipeline.
The doctor engineering Electrical Engineering from the University of Duisburg Germany commented that the chemical, oil and general processes involving fluid transport should have systems of automatic, safe and efficient monitoring to prevent accidents with highly volatile or polluting fluids industry, because they cause a great impact on the environment, damage to society and the economy in general. Therefore, the proposal is to place the system in networks VIVIUNAM distribution control to report to responsible for installing the presence of disturbances and implementing adequate contingency plans.
In various networks, such as system Cutzamala, pumping plant Xotepingo (Mexico City) or distribution networks Pemex pipelines have pressure gauges and fluid, however, use only the data for administrative purposes, instead of using them for leaks and . correct the problem, said Dr. Cristina Verde engineering
The experimental work where leakage is emulated was a pilot 200 meters long pipeline with a diameter of 10.4 inches, instrumented pressure sensors and expense. The VIVIUNAM was operated from a laptop automatically and effectiveness of the algorithms developed by scholars of II-UNAM was found.
The technology used to diagnose leaks is based on mass balances, measured costs, pressure and temperature at the ends of a pipeline without laterals. Each model calibration is performed according to the topology and physical properties and fluid duct in question. This technique is economical because it does not require additional sensors to those available in distribution pipelines, the software only requires data distribution network for the algorithm to work, completed university academic.
