Abstract: Aiming at the situation of power resource shortage comparatively, this paper researched the bi-directional demand management technology applied in load control for the user at power utilization side. From the perspective of application, this paper proposed to use the demand management scheme to realize the reasonable user power utilization control and gave a kind of load impedance detection solution related with the demand management. With the help of this scheme, the relay built in electric energy meter implemented the reliable control and safe closing of high impedance. The site products operation shows that this design could realize the safe and effective staggering peak power utilization.
Key words: bi-directional time-share demand management; load impedance detection; load switch status detection; high impedance closing
