As an important energy production and consumption area, the energy saving and emission reduction performance of thermal power enterprises relates to energy conservation and sustainable development of China’s economy. According to the energy saving policies of power industry, a comprehensive evaluation index system of energy saving and emission reduction performance was built, which contains of energy resource consumption, resource utilization, pollutants emissions and build business efficiency four aspects. The index weights were performed by AHP-entropy weight method considering the expertise and objective information. Meanwhile, an improved Matter-element Extension model was built to evaluate the energy saving and emission reduction performance of thermal power enterprise, in which the domain and standards of maximum degree in traditional model was improved. And an improved correlation function was proposed to instead of traditional correlation function, which is based on both maximum membership degree principle and closeness principles. Finally, the numerical results validate the effectiveness and practicality of the improved model.
This thesis designed a high degree of intelligence charger to solve the Lead-acid batteries’ problems. The design of charger including two parts, hardware design and software design. PIC16F877 is the core control component in hardware part, on this basis, design the corresponding peripheral circuits .And the designing of hardware circuit and driver software of the whole system is explained in detail.
