Comprehensive Solution for Substation Step Voltage Regulators: From Working Principles to Future Trends
1. Working Principle and Technological Evolution of Step Voltage RegulatorsThe Step Voltage Regulator (SVR) is a core device for voltage regulation in modern substations, achieving precise voltage stabilization through tap-changing mechanisms. Its core principle relies on transformer ratio adjustment: when voltage deviation is detected, a motor-driven system switches taps to alter the winding turns ratio, adjusting the output voltage. Typical SVRs provide ±10% voltage regulation with
