Studies on wireless data-collecting system of thermodynamic properties of steam turbine

Tests of thermodynamic properties will be needed before and after overhaul of steam turbine units, in order to assess the economical conditions of the equipment, and to provide directions for operation of Electricity Plant and maintenance tasks in a power plant, to guarantee coal-and electricity-saving, more generation and supplies to offer indispensable preconditions under which an economic dispatching solution and operation of the plant and the system. The existing tests most adopt wired data collecting manner, require complicated testing means and longer cycles. This document raises a set of complete wireless data collecting system based on NRF9E5 Data-collecting Modules for measurements of thermodynamic properties of a steam turbine. This system possesses advantages such as multiple test points, ease of extension, perfect interference resistance.
