Abstract
At operation of the gas-distributing unit (GDU) existence of a reliable data of power of the gas-turbine drive is necessary for management of a duty of the gas transmission system and timely determination of technical condition of a gas-distributing inventory. In work the assessment of accuracy of determination of operational values of power of GDU by the techniques approved by the specifications and technical documentation of Gazprom in the conditions of the concrete compressor station is carried out. Taking into account the accepted assumptions: distribution of the making errors corresponds to the normal distribution law of Gauss and components of errors have no correlation communication, are considered as independent from each other, the main dependences of influence of biases of the GDU parameters (temperatures, pressure, rotation frequencies of rotors) are brought to an error of power rating of GDU. As the error of power rating depends on a method and conditions of measurement, quality of measuring apparatuses and other factors, power rating with a margin error 1.5%-2%, will allow to use its values in the GDU diagnostic models and regulation of a duty of the gas pipeline.
