Latest Patents
One of Hachidai Ito's latest patents is a "System for protecting and controlling substation main circuit components." This invention relates to a system designed to protect and control the main-circuit components of an electricity transmission substation. The system includes devices for digital data output, protection-and-controlling, component controlling-and-monitoring, and communication. The digital data output devices input analogue AC electric values and output digital data. The protection-and-controlling devices input the data from the digital data output devices, and further control, monitor, and protect the substation main-circuit components. The component controlling-and-monitoring devices receive commands from the protection-and-controlling devices or from the substation controlling-and-monitoring equipment, and further control and monitor the substation main-circuit components. The devices for digital data output, the protection-and-controlling, and component controlling-and-monitoring are disposed near or within their corresponding substation main-circuit components.
Another notable patent is the "Digital protective relay system." This system is capable of synchronizing sampling timing among multiple protective relay devices that operate independently by utilizing a signal from a GPS satellite. The sampling timing is made consistent regardless of the time lag from which it is sent downstream, as well as the concomitant transmission delay time in the case of data communications.
