PBS-2000 Power Metering and Billing System Introduction
To meet the requirements of commercialized power management, the PBS-2000 power metering and billing system is designed on the principle of accuracy, reliability and security, to guarantee the equity of power metering and billing for all sides in the power market such as electricity suppliers, vendors, and purchasers. Main functions of the metering and billing system are power quantity acquisition, calculation and balancing with the consideration of assessment function for bus power balancing, line loss, network loss and transformer loss, etc. Automatic acquisition and accounting can be made on power quantity of various junction points with different load nature and relevant data. Pulse kilowatt-hour meters and intelligent kilowatt-hour meters can be connected.
