Development of Packet-Power Transmitter for Realization of Open Access in PowerNetwork

在包含多个主体的电力系统中，主体或参与者采取复杂的经济行为以获得最大的利益。我们的研究目标是开发一种分组电力发射机，以实现电网中所有实体的开放和均匀接入。在我们的研究中，分组功率是指一种具有一定传输功率交易和相关信息的胶囊功率，如“从哪里到哪里”等。为了在实际的电力系统中实现这一概念，我们必须开发基于GPS-internet的家庭电源出口信号在电网中的广域动态监测装置。发电机惯量在电网中的相互作用导致了电力系统中电压相角波动的多种模式。在包括各类发电机组和交易主体在内的竞争日益激烈的环境下，实时测量电力波动将成为动态电力系统状态的重要监测参数。我们使用由八县工业大学和东芝合作开发的基于GPS-internet的PMU单元测量了八县、仙台（距八县约300公里）和东京（距八县约700公里）之间的相位角波动。我们工作的独特之处在于电压信号的测量点。为了提高移动能力和测量的简单性，电压相角的测量采用基于GPS-internet的装置，通过偏远地区的家庭电源插座同时进行。在本研究中，我们能够证明所提出的监测系统的可行性。基于GPS-internet的设备的特点是[采样时间：0.02 s ~ 1s，连续数据长度< 36,000]。该监测系统的设置和观测数据的传输可以通过网络媒体从远程点完成。由此，我们可以考察在不断发生内在振荡的竞争环境下，电网中消费者和其他利益最大化主体的行为。对于包功率的概念，我们可以通过本研究经费开发的监测系统，通过分析所获得的观察结果来确定具体的设计。少

In the electric power system included multiple entities, entities or players take the complicated economic action by which they are able to get maximum benefit. Target of our research is the development of a packet-power transmitter for realization of open and homogeneous access for all entities in the power network. In our research, the packet power means a kind of capsule power with a level of the transmitted power transaction and the related information, such as 'from where to where by whom' and so on. In order to realized this concept in the real power system, we have to develop the monitoring devices of wide area dynamics in the power network through home power-outlet signal by GPS-internet based system. Interaction of generators inertia through power network induces multiple modes of voltage phase angle fluctuation in the power system. Measurements of the real time power fluctuations would be the important monitoring parameters of dynamic power system status especially under the … More competitive circumstance including various types of generation units and trading entities.We have measured the phase angle fluctuation among Hachinohe, Sendai (about 300 km from Hachinohe) and Tokyo (about 700 km from Hachinohe) by using the GPS-internet based PMU units, which was developed by the collaboration of Hachinohe Institute of Technology and Toshiba. Unique point of our work is in measure points of voltage signals. For enhancing the mobile ability and simplicity of measurement, the voltage phase angles are simultaneously measured through the home power-outlet at the remote area by GPS-internet based units. In this research, we are able to demonstrate the feasibility of the proposed monitoring system. The GPS-internet based device is featured as [sampling time : 0.02 s〜1s, data length < 36,000 continuously]. The setting of this monitoring system and the transfer of the observed data can be done through internet-media from the remote point.As a result we are able to survey the consumer behavior and the other entities of maximizing their profit under the competitive circumstances in the power network, in which the intrinsic oscillation occurs continuously. Concerning the packet-power concept, we are able to establish the concrete design by analyzing the obtained observation through the developed the monitoring system by this research grant. Less
