The Far East cogeneration development

This article considers the heat and power supply system based on small and medium- sized cogeneration at the “Vostochnaya” combined heat - and - power plant (GTU - CHPP “Vostochnaya” in Vladivostok) and the “Yuzhno-Sakhalinskaya” CHPP-1 (power units 4 and 5 of the GTU in Yuzhno-Sakhalinsk). This cogeneration is aimed at developing the southern region of the Far East and boosting its energy capacity. The article describes the main equipment such as General Electric LM6000 gas turbine units installed at the GTU - CHPP “Vostochnaya” and at power units 4, 5 of the GTU in “Yuzhno-Sakhalinskya” CHPP-1. Heat energy consumption during the heating period of 2018-2019 at “Vostochnaya” was 787.5 thousand Gcal. The specific reference fuel consumption for electric generation was 230 g/kWh, for heat supply - 121.9 kg/Gcal. Heat energy consumption during the heating period of 2018 at the power units 4 and 5 of the GTU in “Yuzhno-Sakhalinskaya” CHPP-1 was 321.59 Gcal. The specific reference fuel consumption for electric generation was 296.1 g/kWh, for heat supply - 124.7 kg/Gcal. Despite the underutilization of GTU - CHPP “Vostochnaya” in terms of electric and thermal energy (the consumption volumes of connected consumers are less than the design loads), the equivalent fuel consumption indicators reflect the efficiency of GTU generating equipment.
