INDUSTRIAL WIRELESS SENSOR NETWORKS AS A TOOL FOR REMOTE ON-LINE MANAGEMENT OF POWER TRANSFORMERS' HEATING AND COOLING PROCESS

Industrial Wireless Sensor Network used for supervising of high power transformer cooling system is presented in the paper. Due to the fact that in the thermal power plant where industrial prototype is installed is very noisy environment, a lot of problems should be solved in order to obtain high reliability and accuracy of the system. Results of the analysis presented in paper are obtained from the real thermal power plant where presented wireless sensor network based on-monitoring system is used for continuous management of power transformers’ heating and control of their cooling systems. Obtained results during system operation in longer period confirm its stability, accuracy and improvement in power plant operation
