SIMULATION OF THERMAL POWER PLANT SENSOR NETWORK IN ACCORDANCE WITH THE ARCHITECTURE OF "SENSOR-CLOUD"

Abstract

The peculiarities of the sensor networksuse in monitoring systems of thermal power facilities are considered.
Algorithms for automated control of sensor networks of thermal power plants were evaluated in accordance with input data of
sensors and a decrease in the load level on the computing resource of the hardware and software platform. A methodology
has been developed for constructing, configuring and optimizing algorithms for machine analysis and organizing the
operation of a sensor network organized in accordance with the concept of the "Internet of Things". The modeling of the
sensor network control system based on the mathematical apparatus, which determines the areas and sub-areas of the limiting
nodes, has been carried out. The priority of using greedy algorithms in this area for selective activation of sensor network
nodes is indicated. The proposed method made it possible to determine the boundaries of the control objects of the thermal
power plant infrastructure model in accordance with the input data coming from the sensors of the activated nodes of the
sensor network. It is shown that the developed mathematical model makes it possible to achieve high rates of accuracy in
detecting changes in the operating mode of control objects of the thermal power plant infrastructure in conditions of a
decrease in the load on the computing resource of the hardware and software platform.
