| According to the present scarcity of the resources, destroy to the whole environment, the conflict between supply and demand and the influence of the idea on continuable development, it becomes more important than before to optimize power supply, and the development of reproducible energy sources has been the main direction in the procedure of power supply construction.But the main reproducible energy sources such as wind energy, solar energy, and nuclear energy can not be used widely. But the enhydrous energy has been the main aspect for its cleanliness.It is necessary to put forward the research and comparisons on two kinds of power plants, hydroelectric power plant and fossil-fuel plant. At present, there are only limited studies on it. This paper's focal point is to discuss the advantages and disadvantages between the two kinds of power plants, and to compare the macroscopical and microcosmic aspects, then to carry the point on optimizing power supply and ensuring the development direction of power plants. There're totally five chapters. The first chapter is introduction. The second one is the comparisons of the two kinds of power enterprises in macroscopical aspects. The third one is the comparisons of the two kinds of power enterprises in microcosmic aspects. The fourth chapter is to prove the result by an example. The fifth one is conclusion and prospect. The following studies have chiefly been carried on in thesis:1. Deeply discussing the different influence on the two kinds of enterprises by power system revolution.2. Describing the current policy established by the government on the two kinds of the power enterprises.3. Apt to the requirement of the idea on continuable development, doing with the environment protection as an emphasis.4. Discussing the financial performance from three aspects, the financial benefit, the repaying ability and the growing ability.5. On the basis of the above studies, proving the development of hydropower inevitable and necessary. |
