Utilities & Substations
In power generation and substation environments, uninterrupted and stable DC and AC power is essential for grid stability, plant safety, and critical system protection. DEWEN™ designs and manufactures robust UPS systems, DC power solutions, and industrial converters engineered to meet the demanding conditions of utility-grade applications.
🔋 Industrial UPS for Grid and Plant Protection
DEWEN®’s industrial UPS systems are engineered to protect sensitive substation and generation assets including:
- SCADA systems
- Control circuits
- Protection relays
- Communication and automation panels
With double-conversion topology, hot-swappable modules, and remote monitoring, these systems ensure continuous operation and fast recovery during blackouts, load shifts, or grid fluctuations.
⚙️ DC Power Systems Compliant with IEC 62040-5-3
Our DC UPS and rectifier systems are specifically designed to support:
- Trip/close coil circuits
- Battery banks for control power
- RTUs and telemetry panels
in substations and control rooms.
These systems conform to IEC/BS EN 62040-5-3 — the global standard for DC output UPS performance — and offer:
- Redundant rectifier modules (N+1 architecture)
- Temperature-compensated charging
- Alarm relays for fault and battery events
- Built-in diagnostics for substation integration
Their rugged IP54 enclosures and thyristor or modular topologies ensure stable operation in harsh industrial zones, including thermal plants, offshore grids, and transmission substations.
🔄 Power Conversion Solutions for Critical Utility Loads
DEWEN’s frequency converters and inverters deliver precision control for sites managing:
- Black start conditions
- Variable generation loads
- Control of isolated voltage domains
These solutions offer full compatibility with BMS, SCADA, and utility control protocols, ensuring seamless integration and real-time status communication.
