Design of prepayment implementation and its data exchange security protection based on Power Metering Automatic system

This paper describes a prepayment implementation method based on Power Metering Automatic system. This method realizes prepaid functions such as electricity charge owing warning and remote power cutting, by timing Acquiring power consumption information, real-time monitoring remaining power capacity or electric cost and cooperating with marketing management system using load management terminal and concentrator. While for the complexity of GPRS/CDMA communication and on-site electricity environment, the paper makes a number of specific measures designed to ensure data exchange security and stability of prepaid functions.

Design and Development of Provincial Master Station of Metering Automation System of Guangdong Power Grid

In recent years, Guangdong Power Grid Corporation has built the largest scale electric energy metering automation system in the country. The province’s 21 Power Supply Bureau have been building master metering automation systems. Because the data scattered in the 21 Power Supply Bureau’s master station, the data can not be the province’s electricity supply integrated display. There is an urgent need to construct a provincial master station, get the Power Supply Bureau’s master station data, process and integrated display the province-level data. In this paper, considering the actual situation of Guangdong Power Grid Corporation, we design and develop a Provincial master station of metering automation system of Guangdong Power Grid. We use advanced SOA and J2EE architecture, and apply a unified data format, get the power supply bureau’s master station data, calculate totals and overall show. After two years development and construction, Provincial Master Station of Metering Automation System of Guangdong Power Grid achieved good effect for the Guangdong Power Grid production and marketing business.
