摘要： PROBLEM TO BE SOLVED: To maintain the power quality in a distribution system in which many distributed power sources are linked. SOLUTION: A quality control center 1 delivers and receives the information to and from a distribution and transformer station control system 3 and each customer via communication lines 41, 42. The quality control center 1 monitors the system state of the customers' power source operation data and distribution system on line. As a result, if a voltage control value is deviated, the quality control center 1 selects the corresponding system control device and the customer's distributed power source, cooperates them, calculates their control values, and transmits the control values to the customer (for example, A) and the distribution and transformer station control system 3.

摘要： PROBLEM TO BE SOLVED: To provide a highly accurate diagnosis result without being affected by the occurrence time of zero-phase voltage. SOLUTION: The zero-phase voltage V0 is peak-held on positive and negative polarities, respectively, to obtain a waveform attenuated with a definite time constant (in the vicinity of electrical angle 120°). The effective value of this waveform is calculated and compared with a predetermined setting value. If the effective value is larger as a result of comparison, a ground fault exists. Then, respective phase voltages found by phase-converting line voltages to calculate the effective value, thereby finding the sum totals of their products to employ the maximum value of them. As a result, the ground fault can be detected on the phase presenting the maximum value. COPYRIGHT: (C)2006,JPO&NCIPI
摘要翻译：要解决的问题：提供高精度的诊断结果，而不受零相电压的发生时间的影响。
解决方案：零相电压V0分别在正极和负极上保持峰值，以获得以一定时间常数（电角度120°附近）衰减的波形。计算该波形的有效值并与预定的设定值进行比较。如果作为比较结果的有效值较大，则存在接地故障。然后，通过对线路电压进行相位转换而求出各自的相位电压，以计算有效值，从而找出其乘积的总和以使用它们的最大值。因此，可以在呈现最大值的相位上检测到接地故障。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To solve the problem that the use of an extension unit, which is provided for extending a bus and in which a bus phase is replaced when the bus phase is replaced in a conventional gas-insulated switchgear, enlarges the Bay interval of the entire gas-insulated switchgear large and that increases its mounting area. SOLUTION: A bus phase replacing part is provided inside the same bus tank in a conventional Bay interval without providing a separate unit for extending the bus coupled with the breaker of other Bay. As a result, the structure for replacing the bus phase is achieved without using the extension unit by keeping the same mounting area of the entire conventional gas-insulated switchgear as it is.
