摘要： PROBLEM TO BE SOLVED: To solve various problems lying in a power interchange such as in an idea of using storage batteries for power interchange, as the idea is premised on the installation of the storage batteries as showed in conventional examples, the idea makes it hard to response quickly in a case the power to be interchanged exceeds the maximum stored amount of the storage batteries, because the solution is a new installation of the batteries, or such as in a method of executing a power interchange (for example by using a self-excitation type BackToBack), considering the cost of devices and time for the installation, as a capacity per one site being 100 MW or less, more economical and convenient method is desired.SOLUTION: To solve the problems, the present invention executes a power interchange by receiving a requested power amount from other power supply area, by specifying storage batteries corresponding to the requested power amount, and by transporting the specified storage batteries to the other power supply area.
摘要翻译：要解决的问题：为了解决诸如在使用蓄电池进行电力交换的想法中存在的电力交换中的各种问题，作为在传统示例中所示的蓄电池的安装的想法，因为解决方案是电池的新安装，或者在执行电力交换的方法中（例如通过以下方式进行电力交换的方法），在要互换的电力超过蓄电池的最大存储量的情况下很难快速响应使用自激式BackToBack），考虑到设备成本和安装时间，每个站点的容量为100MW或更小，需要更经济和方便的方法。解决方案：为了解决这些问题，本发明通过从其他电源区域接收所请求的电力量，通过指定与所请求的电力量对应的蓄电池，并且将指定的蓄电池运送到另一个电源区域来执行电力交换电源区。版权所有（C）2013，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To prevent excess and deficiency control of the load control amount from occurring due to a difference between the power generation capacity of a generator which is adopted in the pre-operation and the power generation capacity of a generator just before drop-out, and causing deviation from a variation range of allowable frequency or the reference frequency in a pre-operation frequency stabilizer adopting on-line data.SOLUTION: When the power generation capacity 35 of the generator just before drop-out is taken into a stabilizer 2 which is operating a load control amount of each generator from on-line data, a difference decision means 24 and a correction load control amount decision means 25 calculate a correction control amount for a load control amount decision means 22 which corrects the pre-operation results and determines a proper amount of load interruption. Difference of the power generation capacity is corrected for the pre-operation results, and a proper amount of load control is determined by a low-burden simple operation, thus maintaining the allowable frequency.

SOLUTION: In two pairs of communication cables, an FSK transmitter 4a transmits a low frequency signal for communication using a low frequency band to an FSK receiver 5b through a first pair communication cable 6a in one direction, and an FSK transmitter 4b transmits a low frequency signal to an FSK receiver 5a through a second pair communication cable 6b in the other direction. A high frequency signal with a high frequency band transmitted/received by OFDM transmitters/receivers 10a, 10b, 10c, 10d comprises at least three or more carriers arranged at an equal frequency interval, and data allocated to the carriers are changed depending on a transmission state. The high frequency signal with the high frequency band transmitted/received by the OFDM transmitters/receivers 10a, 10b, 10c, 10d is transmitted through the two pairs of the communication cables 6a, 6b in two ways. The low frequency signal and the high frequency signal are superimposed one on the other. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To suppress generation of leakage radio wave on a power line in power line carriage communication.
SOLUTION: A modem A108 is provided in the wires of a single phase three-wire system on the secondary of a pole transformer 102 and power line carriage communication is performed with a modem B109 in a subscriber's premise 100. Since an earth wire 106 is connected with the neutral line of power lines, i.e. the N phase 104, ground impedance is unbalanced between the N phase power line 104 and the W phase power line 105 and a common current Ic is generated. Ground impedance of the N phase is increased for the communication frequency by loading a clamp coil 107 to the earth wire 106 thus reducing the common current Ic and suppressing generation of a leakage radio wave 113.
