Abstract

The invention provides a semi-physical simulation device and a simulation method for a combined gas turbine and gas turbine power generation unit of a ship, and relates to a simulation device and a simulation method for the combined gas turbine and gas turbine power generation unit of the ship, aiming at solving the problem that the existing combined gas turbine and gas turbine power generation unit is low in simulation precision and higher in risk of the test process. Aiming at the simulation demand of the combined gas turbine and gas turbine power generation unit of the ship, a practical physical part is added on the basis of digital simulation of the conventional computer, so that a simulation system is more approximate to the running status of a real machine, and is high in simulation precision. Meanwhile, after simulation is carried out on the combined gas turbine and gas turbine power generation unit of the ship by the semi-physical simulation device and the simulation method, the test debugging quantity of a full-physical test table can be greatly reduced, tests which cannot be performed under the status of the real machine can be performed, and the test security can be greatly improved. Therefore, the invention is applicable to the semi-physical simulation for the combined gas turbine and gas turbine power generation unit of the ship.

Description

technical field [0001] The invention relates to a simulation device and a simulation method of a ship combustion-combustion combined power generating set. Background technique [0002] At present, the use of combustion-fuel combined power plant as the prime mover of the power generation module of the ship's integrated power system can effectively reduce the number of generators and related auxiliary equipment, thereby reducing the total weight of the ship and greatly reducing the life cycle cost of the ship. Therefore, mastering the dynamic operating characteristics of the marine fuel-fired combined power generator set is the key to design and develop a unit control system with reliable performance and stable operation. Although the traditional computer digital simulation is flexible in configuration, it makes many assumptions about the actual device and operating conditions, and it is difficult to guarantee the accuracy; and the cost of the full physical test bench is very ...
