A computer-aided facility for testing gas-turbine power stations

详细

Structural and parameteric synthesis of an automatic control system for gas-turbine power stations complicated by the complexity, nonlinearity, and multimodality of the control object, which is both the gas-turbine power station itself and the associated electric-power system, is conducted using the simplest possible mathematical models. The development of simulation models of the electric-power systems of various structures and element compositions and analysis of the functioning of the latter when reproducing a given list of external and internal disturbances are a topical task. The conditions of a test stand offer the possibility of combining the stages of computer-aided tests, i.e., simulation of the automatic control system, and semirealistic tests, i.e., tests of mockups and experimental and pilot prototypes, using a computer model of the electric-power system. The development of program modules for simulation of the electric-power system is considered. The modules are integrated into a subsystem for testing power-generating plants. The use of the Java language facilitates the cross-platform properties and universality. The computation of the dynamic modes is represented as a sequential computation of the static modes in every sampling step. Models of the elements of the electric-power system have been developed.
