Product Application

The bi-directional energy meter is mainly aimed at the users who need two-way measurement in distributed PV solar power station. When the electricity generated by the PV solar power station is surplus, the power transmitted to the grid needs to be accurately measured; when the PV solar power generation can not meet the needs of users, the power consumption of the grid also needs to be accurately measured. However, the common single one-way ammeter can not meet this requirement, so it is necessary to use digital power meter with bidirectional metering function to realize bidirectional metering of electric energy.

In distributed PV solar power station, if the bi-directional energy metering of power consumption and power generation is realized, the traditional way is to use two digital energy meters to measure power generation and power consumption respectively, which greatly increases the use cost, increases the difficulty of wiring, and becomes complex in future use or maintenance. In order to realize remote meter reading, one more communication line and one meter are needed Both increase the difficulty of use and push up the use cost, which is not conducive to a large number of popularization and application; and the use of two-way meters, only a two-way meter can be used to achieve the electricity fed into the grid, and the power consumption of the grid can be measured separately. Compared with the previous scheme of using two one-way meters, the scheme has the advantages of lower cost, less construction difficulty, more convenient maintenance and simpler use, which is also a photovoltaic power station The two-way electric energy measurement based on GIS provides the best measurement application scheme.
