Ripple control generally refers to systems that are applied to electrical networks for demand side management purposes. They offer a means of communication from a central point to any point on the LV network for action at end-users' premises. Ripple control is mainly dedicated to mass applications but individual and specific applications can also be addressed.
Applications are easily programmed by the operator in control consoles and receivers (Stand-alone receivers beside the meter or receiver integrated into electronic meters).
The principle consists of superimposing on the voltage network a small signal at the ripple control frequency. The injection can be made on either an MV or HV network at the transformer substations.
The communication reliability has proved to be very close to 100%, authorising critical applications such as tariff switching, direct and dynamic load control and street lighting control.
