摘　　要：海洋温差能是一种可再生的绿色能源,储藏量大,资源稳定。海洋温差发电是利用深层、表层海水的温度差,以高温海水为热源,使液态工质气化推动发电机发电,以低温海水为冷源,使气态工质液化的不断循环的过程。基于能源的可持续发展考虑,可以利用风能、太阳能等可再生能源来优化设计海洋温差发电系统。华东沿海海域有着丰富的太阳能和风能资源,利用太阳能可以提高表层海水与深层海水的温差,利用风力转化装置可以提高和调整汽轮机的转速,保证发电系统持续稳定的发电。利用太阳能、风能对海洋温差发电系统进行优化设计,不仅避免和解决了当前海洋温差发电技术上的一些难点,还扩大了应用温差能资源的海域范围。Ocean thermal energy is a sustainable green energy with large reserves and stable resources. The principle of ocean thermal energy conversion is： the liquid medium will be made to vaporize by the surface of the ocean, and the vapor will promote the generator for power. Then the deep layer of the ocean will make the vapor liquefy and continue to work as medium. Based on considerations on sustainable development of energy, ocean thermal energy system can be opti- mized by using of a range of other renewable energy resources solar energy and wind energy. Coastal area of East China is rich in solar and wind energy resources. The use of solar energy can improve temperature of the sea surface, then increase temperature difference between surface and deep layer of the ocean. The use of wind power conversion device can increase and adjust the speed of gas turbine power generation to ensure continuity and stability. The new thermal energy system used the renewable energy resources is considered to have great potential. It will not only effectively avoid and resolve a number of technical difficulties about the current thermal energy, but also expand the application temperature range of the sea resource.
