Development And Application Of The Power Load Management Terminal Unit

Power load management terminal has played an increasingly important role in the power end users, but the limitations of the data sampling range and energy source’s reliability has put some power limits on its importance.. With the rapid development of communication technology and efforts to build smart grid, load management and client risk exclusion will be the focus of future development Electric load terminal which has been popularized as a field devices, become a medium of centralized data collection, uploading and remote task given.At present power load management terminal and main system is mainly used for data collection, storage, remote telecommunication which include power consumption, need, voltage, current, power and power factor, power quality in order to provide various types of settlement data for the power marketing system, control and manage the load of large user, realize load shifting and orderly electricity consumption, real-time monitor the operation of large users’meter, Based on analysis of the current situation of power load management terminal and defects, propose the related solutions.Comprehensive analysis of the technical principles and techniques load management terminal and relay terminals to achieve, and targeted measures proposed to resolve this paper. By taking increased terminal adapter hardware, software upgrades, power and transformation techniques to increase the power load management terminal for relay equipment data acquisition, load management terminal through "full coverage, full capture" information network, to achieve the following electrical protection terminal system "full coverage, collector", also achieved metering circuit, data protection circuit schematic two relatively independent systems integration. Improve the collection of data on the state of the power grid, analysis, management, terminal alarm sound judgment function. For the establishment of a smart grid, strong grid building blocks.By David Teng Electrical Co., Ltd. Ningbo client site and install a new terminal adapter commissioning applied research to promote the further development of new features and power load management terminal played an exemplary role.
