(1) The head investigator A.Nabae proposed a new definition of the Instantaneous Active-reactive Currents and Powers using polar coordinate. Based on the new definition, the research team has developed a new series active capacitance for three-phase power systems, which is able to compensate both harmonics voltage drop and phase angle delay of fundamental component caused by the system's impedance. The dynamic behavior was analyzed theoretically and satisfactory results have been obtained from computer simulations.(2) In order to establish a best control algorithm, it is required to analyze a control system including rotating coordinate transformation. Then, a new complex transfer function applicable to 2-input and 2-output system was introduced and it was shown that the complex transfer function analysis was effective in analyzing the control system.(3) Power source frequency fluctuates always within a range of (]SY.+-[)0.1Hz, and its detection method was one of the important problems to be solved. The project team has established a new detection method of the fundamental wave, in which rotating coordinate transformation is used and the fundamental frequency can be instantaneously detected.As the results of this research project, the series active capacitance will contribute to solve power system stability problem and power flow sharing problem of 2 parallel transmission systems.

(1)首席研究员a . nabae用极坐标提出了瞬时有功无功电流和功率的新定义。基于新定义，研究团队开发了一种新型串联有源电容，用于三相电力系统，能够补偿系统阻抗引起的谐波压降和基元相角延迟。对其动力特性进行了理论分析，并通过计算机仿真得到了满意的结果。(2)为了建立最佳控制算法，需要对包含旋转坐标变换的控制系统进行分析。然后，引入了一种新的适用于二输入二输出系统的复传递函数，并证明了复传递函数分析对控制系统的分析是有效的。(3)电源频率始终在（]SY.+-[）0.1Hz范围内波动，其检测方法是需要解决的重要问题之一。项目组建立了一种新的基波检测方法，该方法采用旋转坐标变换，可以瞬时检测基波频率。作为本课题的研究成果，串联有源电容将有助于解决电力系统的稳定性问题和两个并联输电系统的潮流共享问题。
