When the power system load in a small disturbance, the system itself to maintain the stability of the power transmission capacity, the use of automatic excitation regulator device may reduce the reactance of the generator, and then further to maintain the transformer high-voltage bus voltage constant, so compensation not only its own reactor, but also compensation for the step-up transformer reactance, thus greatly improving the power limits of generators, which greatly increased the static stability of power system.

当电力系统的负载发生微小的扰动时,系统本身保持稳定送电的能力,使用自动励磁调节装置,则可减小发电机的电抗,再进一步维持变压器高压母线的电压恒定,这样不仅完全补偿了自身的电抗,而且还补偿了升压变压器的电抗,这样就大大提高了发电机的极限功率,即大大地提高了电力系统的静态稳定。

Although the measures such as the simulation method with detailed generator model in which the dynamic behavior of exciting system is taken into account and installing power system stabilizers in main generators of Northeast Power Grid were adopted, it was still unable to effectively verify the reasonableness of parameter setting of PSS as well as its integrated matching result, and there was not enough scientific foundation for the selection of power grid model, especially load models. Moreover, it was hard to make accurate quantitative analysis, even though the qualitative analysis, on the close extent of selected models to actual operation of power grid.

This thesis uses DEA to compare the WANO's performance indicators among three nuclear power plants in Taiwan. We take the past 7 years'(1997-2003) data of 3 plants, there are 21 DMUs totally. Due to the importance of the nuclear power plant safety performance , we adopt the output estimation by assuming the input as a constant; Five outputs parameters such as unit capability factor, unplaned automatic scrams are chosen to proceed the comparison and get the relative efficiency. We also collect the WANO performance indicators data of the same type nuclear power plants as Taiwan in the United State during 1999-2003 to proceed the same comparison with the domestic three nuclear power plants , in order to understand the relative efficiency between two groups.
