Stepless compensation and multi-step compensation are two different approaches used in power system compensation to mitigate the effects of reactive power and voltage fluctuations.
The stepless compensation system continuously monitors the power system conditions and adjusts the reactive power output accordingly to maintain the desired voltage levels. It provides smooth and precise compensation over a wide range of operating conditions. The reactive power output can be controlled in a stepless manner, allowing for rapid response and dynamic voltage control.
In a multi-step compensation system, the reactive power compensation is switched on or off in response to predefined voltage or power factor thresholds. When the system voltage drops or the power factor deviates from the set bounds, the compensation steps are activated or deactivated. The compensation levels are discrete and predetermined, offering a step-wise reactive power adjustment.
The choice between stepless and multi-step compensation depends on various factors such as system requirements, cost considerations, dynamic response requirements, and available control technologies. Stepless compensation provides precise and continuous reactive power control, ideal for dynamic load variations and fast response requirements. Multi-step compensation offers cost-effective solutions for static operating conditions where discrete levels of compensation are sufficient to maintain desired voltage and power factor levels.
