Zhejiang Hongyan Electric Co., Ltd. 
SOLUTION OVERVIEW
Engineering scope and operating conditions
Supporting renewable-energy grid connection
Solar inverters, wind converters and energy-storage systems change their output with operating conditions. At the point of connection, the project may need dynamic reactive power support, voltage regulation and harmonic compliance across a wide power range.
Solution elements
- SVG for fast inductive and capacitive reactive power control.
- SVC or MSVC where project capacity and operating strategy require staged high-voltage compensation.
- Passive or active filtering based on the measured or calculated harmonic spectrum.
- Communication interfaces for plant controller, SCADA and remote operating commands.
Project verification
CHYN reviews the grid-code target, point-of-connection voltage, inverter quantity and topology, plant output curve, cable and transformer parameters, harmonic study, ambient conditions and control logic. Capacity and response settings are confirmed against the most demanding operating scenarios rather than a single rated point.
