Problems solved by technology

At present, the gas turbine control system test system usually uses real gas turbines or gas turbine mathematical models as the controlled objects, but real gas turbines have the disadvantages of long construction period, high cost, and risk of damage to equipment and personnel when operating under extreme conditions. The degree is low, and only a small number of operating conditions and partial operating data can be calculated
