At the peak-standby energy sources there are operate four gas receiving stations which provide the specified design parameters of the fuel before it is fed to the turbines.

In the Republic of Belarus, the peak-standby energy sources (PSES) based on Siemens SGT-800 turbines has been constructed and commissioned. At the Minsk CHPP-5, this is a 300 MW gas turbine power plant (GTPP) consisting of six turbines, at the Berezovskaya SDPP – 250 MW GTPP (of five turbines), at the Lukomlskaya SDPP – 150 MW GTPP (of three turbines), at the Novopolotsk CHPP – 100 MW GTPP (of two turbines).



Being in the mode of continued readiness to launch, the facilities will maintain, if necessary, the balance of generation and consumption of electricity. The equipment of the new GTPPs is characterized by high maneuverability – it take less than 15 minutes to responsively start and fill the power deficit in the power grid.

The ENERGAS Company has equipped the Belarusian PSESs with four gas receiving station. GRSs were manufactured by ENERGAS under the special projects and are the gas treatment stations which provide the specified design parameters of the fuel before it is fed to the turbines. The main purpose of GRSs is purification, flow measurement and heating of gas.



All the stations are equipped with a separation system with coalescing filters-scrubbers. The efficiency of gas purification is 99.9% for impurities over 10 microns in size. It is possible to quickly replace the filter-elements.

To measure the volume of fuel entering the gas-turbine power units, the GRSs are equipped with the two-line commercial metering units. Data from them is transmitted via communication channels to the upper level of the automated process control system.

To achieve design gas temperature (up to +40°C), at each GRS there is installed heating module, which composed of heat exchangers and subassembly of gas condensate gathering and storage with a drainage tank.

The process units are equipped with fuel quality control assemblies installed on the outlet pipelines and equipped with measuring and analytical equipment.

The stations are placed in sound- and heat-insulated block-boxes and equipped with necessary engineering systems. GRSs were designed to operate in automatic mode, their throughput is from 29,210 to 87,506 m3 / h, depending on the number of conjugated turbines and the capacity of the PSES.



REFERENCE:

New capacities of the PSESs are aimed at increasing the reliability and flexibility of the Belarusian power grid. Gas-turbine power units are used as a reserve both for the existing infrastructure and for future wind, solar and nuclear power plants. The commissioning of PSESs will contribute to the decarbonization of the economy and the transition to a new energy structure in Belarus. The assumed operating time of each peak power facility is approximately 700 hours per year and up to 350 starts from the cold state.
