This paper presents the working principle of CCHP system, and establishes the static mathematical models of Gas engine, LiBr absorption chiller, Gas boiler and Centrifugal water chiller. In this paper, it establishes optimization mathematical model that makes minimum annual total costs as optimize targets and energy balance as constraint condition; it takes the core area of a tourist resort in Shanghai as the user end, uses MATLAB software to optimize and analysis the research case, gets total annual cost and operating optimization strategy.

Matching optimization of resonant parameters among the high power inverters, low power transformers and plasma reactors have significant effects on the performance and output of the reactor array when applying the partitioned operation method. In this paper, the Matlab/ Simulink electrical model was established based on the method of partitioned operation. The matching relation between resonant parameters is analyzed on the basis of experimental result. As a consequence, transformer leakage inductance and working frequency are the important parameters influencing the operational efficiency of system, leakage inductance of transformer should be adjusted based on the equivalent capacitance of plasma reactor to realize the matching optimization of resonant parameters.
