Working principle
The series of dynamic reactive power compensation cabinets
are mainly composed of monitoring terminal switch modules, capacitors, reactors, circuit breaker cabinets, etc. The controller adopts feedforward or monitoring (three-phase balanced load, single-phase signal collection, three-phase Phase unbalanced load, using three-phase signals) takes the real-time reactive power of the load as the switching physical quantity, and applies the instantaneous reactive power control theory and network voltage support algorithm to complete the signal data collection calculation and control the output switching switch. After the switching instruction, the zero current input is completed within less than 10 seconds. There is no inrush current and no impact on the power grid. Measures are taken in the main circuit and switch to precharge the main circuit capacitors and avoid switching capacitors. impact, easy to operate, more stable, safe and reliable. In order to ensure real-time tracking of switching, the entire system response time is less than 100%, which can meet the needs of rapidly changing loads and achieve rapid compensation.
Scope of application
It is widely used in power supply and distribution systems such as power, metallurgy, railways, military industry, petroleum machinery, chemical industry, ports, light industry, building materials, mines and shipbuilding. It is especially suitable for occasions where dynamic free compensation is required and harmonics need to be suppressed or controlled at the same time. Operating conditions with large and changing wave loads.
