High-position arrangement method and structure of combined main power house of split-shaft gas-steam combined-cycle power plant
The invention relates to a high-position arrangement method and structure of a combined main power house of a split-shaft gas-steam combined-cycle power plant. The high-position arrangement method comprises the steps that 1, a ground layer, a middle layer and an operating layer are arranged in the combined main power house, wherein the operating layer is used for arranging a steam turbine engine generator unit and a gas turbine generator unit, and the ground layer and the middle layer are used for arranging the auxiliary equipment of the steam turbine engine generator unit and the gas turbine generator unit; 2, the central line of the gas turbine generator unit and the central line of the steam turbine engine generator unit are arranged in parallel, the steam turbine engine generator unit is arranged on the left side or the right side of the gas turbine generator unit, and the devices of multiple split-shaft gas-steam combined cycle units are sequentially arranged in the same main power house; 3, the gas turbine generator unit is arranged at a high position in a lower-gas-inlet mode, and the steam turbine engine generator unit is arranged at a high position in a lower exhaust mode; 4, each split-shaft gas-steam combined cycle unit is provided with an overhaul travelling crane, or the split-shaft gas-steam combined cycle units share the overhaul travelling crane so as to overhaul all main and auxiliary engine equipment of each unit. By the adoption of the high-position arrangement method and structure of the combined main power house of the split-shaft gas-steam combined-cycle power plant, occupied area is small, the using rate is high, and the civil engineering cost of the main power house can be effectively reduced.
