Performance Analysis of Thermal Energy System with Linear System Method

The paper addresses the system performance of coal-fired power unit with changed auxiliary system or other localheat disturbance.The idea of state space model is imported and the universal formula for the calculation of sys-tem performance output is deduced on the system state equation.Two important vector of system are worked outunder linear system assumption and transform.The transfer matrix is the characteristics of system itself and isconstant for a similar condition,which greatly facilitates the analysis.The concept of thermal disturbance vectoris proposed to construct the thermal disturbance input easily.The method can be helpful for analyzing any ther-mal disturbance input satisfying the assumption and also for supplementing the correction means of performancetest.An example of 600MW power unit is presented to demonstrate its availability.
