碩士 === 國立高雄應用科技大學 === 電機工程系碩士班 === 93 === This thesis applies optimization mathematical techniques of dynamic programming（DP）algorithm to solve the daily optimal air conditioner loads（ACL） control schedule, and discusses regular control strategies based on different requirements in varied situations . The first proposed control scheme is called regular control mode which supports three control skills of demand control, cycling control and timer control to assist customer to save the electrical fee. The other one is called optimum load control scheme which supports any combinations of these three control skills to optimally save the customer’s electric fee in a specific period of time. In order to cope with the flexibility and uncertaineties associated with constraints on the on/off duration of the ACL, and the uncomfortableness felt by the customers due to the temperature variation, the interrupted capacities of the ACL are regarded as condition variables. Besides, in order to concretely realize the feasibility and effectiveness of proposed controlling strategies, the techniques of microprocessor hardware interface is applied in this thesis. For the ACL customers, the prototype of load controller is developed and implemented to enhance energy efficiency, and to clip the system peak load, and then to save the electrical fee. Visual C++ 6.0 language is adopted as the developing tool to carry out the proposed work. The daily scheduling result will be loaded into energy saving controller as the strategic decision via the RS-232 communication port. The field test of controlling the air conditioner located in the campus is carried out to demonstrate the effectiveness of the proposed load controller.
