Multi-loop bidirectional dynamic electric energy metering device and method

The invention belongs to the technical field of electric power and electric energy metering, and discloses a multi-loop bidirectional dynamic electric energy metering device and method. The multi-loopbidirectional dynamic electric energy metering method comprises the steps of determining the loop number of incoming lines, loads and power branches; configuring alternating current, voltage, a sampling plate, a CPU and a power supply; each branch of the device being connected with a current-voltage loop and a communication loop; setting incoming line/load/power supply parameters; and completingdebugging and putting into operation. The multi-loop bidirectional dynamic electric energy metering device comprises a device panel; an alternating current plug-in, an alternating voltage plug-in, a sampling board, a CPU plug-in and a power supply plug-in are installed on the reverse side of the device panel. The device is provided with more than three sub-loops, each loop has a bidirectional metering function, and meterin
