The protection and management of rivers and other water resources are vital not only as a “lifeline” for public water supply but also as a cornerstone of ecological civilization. Recently, the Chinese government issued the "Opinions on Comprehensively Promoting River Protection and Governance," posing a complex challenge for the water sector: ensuring water supply security while achieving energy efficiency and green transformation.

In this context, water utilities demand industrial equipment with greater stability, flexibility, and operational efficiency. Schneider Electric’s medium-voltage drives, the Altivar 1200C and Altivar 1200C-S series, have proven to be innovative solutions, offering safety, reliability, ease of use, and intelligent efficiency, with notable success in multiple water projects.

A major inter-basin water transfer project aims to alleviate water shortages, curb ecological degradation, and support long-term regional development. However, challenges such as variable daily water demand and frequent pump operation lead to higher fault rates and maintenance costs for motors, pumps, and valves, while stressing the power grid and pipeline network.

Schneider Electric medium-voltage drives provide a “triple guarantee”: unit bypass technology ensures continuous operation during faults; automatic bypass cabinets (“one-to-one” or “one-to-two”) allow rapid switch to utility power; low-voltage ride-through enhances resilience against grid fluctuations. Soft-start functionality reduces mechanical stress on motors and pumps, prolonging equipment life. These capabilities enable precise, demand-based regulation of water flow and pressure, reducing energy consumption and maintenance costs, and delivering both operational stability and economic benefits.

Ensuring Safe Water Supply in Major Resource Allocation Projects

Large-scale water supply projects face high-temperature, high-humidity environments and geographically dispersed systems, making long-distance operation and maintenance challenging. Schneider Electric drives leverage closed-loop water-air cooling, integrated heaters, and unit bypass functionality to maintain reliability. Remote monitoring via Modbus TCP, coupled with Drive Advisor digital solutions, enables predictive maintenance, rapid fault diagnosis, and reduced inspection costs, overcoming geographic constraints. Automatic bypass and soft-start support “on-demand” water supply, maximizing efficiency and minimizing energy waste.

From inter-basin transfers to regional water allocation, Altivar 1200C and 1200C-S drives exemplify automation, digitalization, and green innovation, powering the sustainable development and modernization of the water sector. Schneider Electric continues to provide reliable, intelligent, and energy-efficient solutions, safeguarding billions of people’s daily water needs and promoting harmonious ecological growth.
