OREANDA-NEWS. November 28, 2012. In November 2012, at the Baidaratskaya compressor station the commissioning of six gas turbine units based on Aviadvigatel gas turbines has been completed. The total power of the equipment is 96 МW.

The Baidaratskaya CS is the head compressor station of the Bovanenkovo-Ukhta main gas pipeline system. Further the Yamal gas is transmitted on the following directions: Ukhta - Griazovets, Griazovets - Torzhok, Griazovets - Yaroslavl, Ukhta - Pochinki.

On the Gasprom's order six Iskra-Turbogas GPA-16М-07 gas pumping sets were delivered at the Baidaratskaya compressor station (Gasprom Transgas Ukhta). The PS-90GP-2 engine (Aviadvigatel OJSC is the developer, the Perm Motor Plant OJSC is the manufacturer) is at the heart of each gas pumping set. The units are equipped with the NTz16М/120 centrifugal compressors (Iskra OJSC) with the magnetic suspension apparatus, the SUMP-М2 control system (VNIIEM OJSC) and the dry gas-dynamic seal system (John Crane Inc. -  Iskra).

Taking into account the adverse climatic conditions of Yamal, the gas turbine equipment was manufactured in the hangar version which allows to maintain systems of the gas turbines and the booster in good working order at the ambient air temperature up to -60 0С. Moreover, the hangar version significantly simplifies the work of the station maintenance personnel.

The specific nature of the GTU-16P location within the hangar-type unit determined some design differences of the unit from the baseline model. In particular, in accordance with plans of  Gasprom, for enhancing the environmental friendliness of gas turbines with the hydraulic control system of the compressor mechanical means specialists of the design bureau provided for the start of the PS-90GP-2 engines by means of the STVD-30-D-11T electrical starter.

The maintenance of the station will be performed by the rotational team method using the so called limited manning. This is the evidence of the high level of automation of the installation allowing to combine functions of the current and automatic control of systems.

According to plans of  Gasprom, in future at Baidaratskaya CS one more shop for four gas pumping sets with the unit power of 16 MW made by Perm will be constructed. Therefore the projected capacity of the station will increase to 160 MW.

It should be noted that on this part of the main pipeline three more compressor stations with gas pumping sets are located, developed on the basis of the Aviadvigatel GTU-25P gas turbines ‒ the Yarynskaya CS, the Usinskaya CS and the Gagaratskaya CS. All these stations are projected in the two-shop version, therefore over time the presence of industrial gas turbines developed by the Perm Design Bureau will significantly increase.
