Abstract

The invention discloses an emitter coupling type amplification-based oscillation drive control system of an energy-saving power grid. The system comprises an EMI single-phase filter, a silicon controlled rectifier connected with the EMI single-phase filter, a boost-type power factor correcting circuit connected with the silicon controlled rectifier, a single-phase high-frequency inverter connected with the boost-type power factor correcting circuit, a sampling protection circuit connected with the single-phase high-frequency inverter, a single-chip microcomputer connected with the sampling protection circuit, and a band-pass filtering low-distortion oscillating circuit in tandem connection between the boost-type power factor correcting circuit and the sampling protection circuit. The system is characterized in that a loss suppression circuit is in tandem connection between the sampling protection circuit and the single-chip microcomputer. The loss suppression circuit is capable of preventing the current intensity from being weakened during the current transmission process. Meanwhile, the band-pass filtering low-distortion oscillating circuit is strong in controllability, and stable in current and other performances. Therefore, the energy-saving effect and the security of the system are effectively improved.

Description

technical field [0001] The invention relates to the field of power grid energy saving, in particular to an oscillation control system based on a loss-suppressing energy-saving power grid. Background technique [0002] At present, with the development of urbanization and the improvement of people's living standards, the power consumption of urban lighting has increased geometrically. In response to the call of the national energy conservation and emission reduction policy, the concept of smart grid has been increasingly recognized by everyone. The smart grid is the intelligence of the power grid, also known as "grid 2.0", which is a technical application based on an integrated, high-speed two-way communication network, which can realize the reliability, safety, economy, efficiency, environmental protection and safety of the power grid The goal. [0003] Among them, the frequency conversion energy-saving street lamp is an important unit of the smart grid, and the energy savin...
