5 × 400kW Backup Power Solution For Drainage Pump Station– Taicang, China
Project Background
Taicang is located in the Yangtze River Delta's low-lying plains, where heavy rainfall and river backflow pose frequent flooding risks during monsoon and typhoon seasons.
The Taicang Inner Lake Pumping Station required a high-reliability diesel generator backup system to guarantee uninterrupted power supply during grid outages. Ensuring pump station operation in such emergencies is critical for urban flood protection and public safety.
Project Challenges
Drainage operations require seamless, uninterrupted power, especially during storm surges or citywide blackouts.
The station uses five 400kW diesel generator sets. These units must start, stop, and run in parallel, balancing loads based on real-time pump demand.
Located near water bodies and low-lying terrain, the generators face high humidity, corrosion risks, and potential floodwater exposure.
