有源电力滤波器
An Active Power Filter (APF) mainly mitigates harmonic currents generated by non-linear loads such as VFDs, rectifiers, UPS systems, and inverters. It injects compensating current in real time to cancel harmonics, keeping the grid current clean.
静止无功发生器
A Static Var Generator (SVG) mainly addresses reactive power and the voltage problems it causes: Reactive power compensation: it dynamically supplies or absorbs reactive power (both inductive and capacitive) in real time. Low power factor: it raises the power factor and helps avoid utility power-factor penalties. Voltage fluctuation and flicker: it stabilizes voltage against rapidly changing loads such as arc furnaces, welders, and cranes. Voltage sags and swells: it supports grid voltage, which is especially important for wind and solar plants. Three-phase unbalance: it can balance loads across phases (with phase-separated compensation).
电力转换器
A PCS (Power Conversion System) is the bidirectional interface between a battery energy storage system and the AC grid. It mainly handles: AC/DC conversion: Converts DC from batteries to AC for discharging, and AC to DC for charging. Charge/discharge control: Manages power flow and battery charging/discharging according to dispatch commands from the EMS/BMS. Grid-connected and off-grid operation: Supports seamless switching between grid-tied and islanded modes, providing voltage and frequency support when the grid is down. Renewable integration: Smooths the fluctuation of solar and wind output and enables peak shaving and load shifting. Grid support functions: Provides reactive power compensation, frequency regulation, and fault ride-through.
动态电压恢复器
A DVR protects sensitive loads from voltage sags and swells by injecting the missing voltage in series within milliseconds, keeping the load voltage stable.
