What Is the Significance of the Reactive Power Demand Curve in Designing an Effective Low Voltage Reactive Power Compensation System?

In the field of modern power system optimization, the reactive power demand curve acts as a silent translator, converting the invisible language of the power system into a visual technical map. This curve, which records the variation of reactive power over time, not only reveals the dynamic characteristics of the load but also serves as the core compass guiding the design of low-voltage reactive power compensation systems towards precision and efficiency. Understanding the profound meaning of this reactive power demand curve represents a crucial step for low-voltage reactive power compensation technology in moving from empirical configuration to scientific design.

Decoding of Load Characteristics and the Cornerstone of System Architecture

The shape of the reactive power demand curve is a true reflection of the load characteristics. A smooth curve indicates that the motor equipment is operating stably, while a violently fluctuating curve suggests that load equipment such as welding machines and cranes frequently start and stop. Engineers analyze the peaks, troughs, and rate of change of the curves to accurately determine the range of reactive power demand and dynamic response requirements of the system. This directly determines whether the compensation system should choose static compensation or dynamic compensation, and whether a hierarchical switching strategy is needed. The fluctuation period of the curve also provides a basis for calculating the service life of capacitor switching, avoiding premature aging of equipment due to frequent operations.

The Orientation of System Optimization and the Key to Energy Efficiency Improvement

A comprehensive analysis of the reactive power demand curve can reveal potential opportunities for enhancing the energy efficiency of the power system. The continuous capacitive reactive power interval in the curve indicates the risk of excessive compensation, while the long-term inductive reactive power peak implies severe energy waste. By superimposing the reactive power demand curve with the active power curve for analysis, the periods with the lowest power factor can be precisely identified, and efforts can be made to achieve the optimal investment in low-voltage reactive power compensation systems. For curves with periodic patterns, predictive switching strategies based on time logic can be designed to upgrade the compensation system from passive response to active management. This optimization based on in-depth analysis of the reactive power demand curve typically can enhance the energy efficiency of the power system by 3-5%.
