At the test ground for rocket and space technology of the Proton-Perm Motors PJSC (Proton-PM), there is a complex for testing gas turbine units (GTU) with a capacity of up to 40 MW.

In December 2011, the ENERGAS Company installed here a booster compressor station (BCS) for fuel gas. The BCS feeds the testable turbines with gas that meets the specified parameters in terms of purity, temperature, pressure and flow rate. This equipment was specially devised to operate in conditions of various tests duration and high intensity of starts.



The project requirements for the gas purity are ensured by the multistage filtration system of BCS: inlet protective strainer, gas-oil separator of the 1st stage of purification and coalescing (safety) filter of the 2nd stage. Thus, compliance of the fuel with the set norms is guaranteed: the content of mechanical impurities in gas at the outlet is no more than 2 ppmw (mg / kg), the degree of purification from solid particles larger than 10 microns and liquid fraction is 100%.

Highly efficient compressor module gives a high gas compression ratio: the pressure at the suction is 0.5 MPa, the pressure at the delivery line can be provided in the range of 1.6 ... 4.5 MPa – depending on the type and settings of conjugated GTU and the testing algorithm.

The process flow scheme provides for the stable maintenance of the calculated fuel temperature. The delivery line of the BCS is equipped with a shell-and-tube heat exchanger that cools the working medium and guarantees the optimum gas supply temperature set by the turbo unit manufacturer.



The volume productivity of compressor station varies from 2,500 to 11,000 m3 per hour. The actual gas flow rate depends on the capacity and dynamics of the load of associated turbine, and is controlled in the range from 0 to 100% of nominal. For this purpose, a special two-tier productivity regulation system is used, which allows the BCS to respond as quickly and correctly as possible to changes in the operating mode of the testable GTU and fluctuations in the parameters of the inlet pipeline, as well as, if necessary, to operate the station in the gas recirculation mode.

Packaged BCS is fully automated and is housed in its own all-weather shelter, equipped with life support systems (heating, ventilation, and lighting). According to safety requirements, process unit is equipped with fire detection, gas detection, alarm and fire fighting systems.

For the ENERGAS Group, this is the first project completed for power engineering enterprises. Subsequently, by specially designed compressor stations there were equipped gas turbines test benches of CJSC Nevsky Zavod, PJSC UEC - Ufa Motor-Building Production Association and JSC UEC - Gas Turbines.



The first in Russia multi-purpose adaptive test bench for gas turbine units is a joint project of Proton-PM and Perm National Research Polytechnic University. The uniqueness of the technology proposed by Perm engineers is confirmed by Federal Service for Intellectual Property.

The test bench has become one of the major structural elements of technopolis Novyi Zvezdnyi within frames of the innovative direction Power engineering. GTU tests are carried out in the interests of the various design offices, pilot plants and factories, specializing in the manufacture of gas turbine units.

The technical solutions implemented here allow testing equipment of various modifications. The basis for an objective analysis of the reliability and efficiency of GTU is being created by measurement system that is able to reliably determine the unique number of parameters of both the testable units and the test bench itself.
