GWPC-EXC Generator Excitation Control Panel

Desc

The GWPC-EXC Generator Excitation Control Panel is an essential control component of excitation systems for synchronous generators with ratings up to 300 MW. It continuously measures generator-terminal voltage, stator current, frequency, reactive power, power factor, and other operating quantities, and regulates the DC output of the thyristor rectifier accordingly. The controlled excitation output maintains the generator-terminal voltage at the required level and enables the generating unit to meet its reactive power control requirements during grid-connected operation.
The GWPC-EXC provides automatic voltage regulation, manual field current control, operating limiters, logic control, fault monitoring, HMI, and communication functions. Depending on the generator rating, excitation method, and project requirements, the power rectifier, field-flashing unit, de-excitation unit, and excitation transformer may be supplied as integrated assemblies or as separate panels and equipment.
The panel is widely used in hydropower plants, thermal power plants, industrial captive power plants, biomass power plants, waste-heat power generation facilities, and other facilities that operate synchronous generators. It plays an important role in ensuring the safe, stable, and efficient operation of the generator.

WPC-SYN generator automatic synchronizing panel by GoWatron

GWPC-SYN Generator Synchronizing Panel

The GWPC‑SYN Generator Synchronizing Panel is designed for the automatic synchronization and grid connection of synchronous generators in hydroelectric, thermal and other power plants. It is typically installed in the central control room alongside the GWPC300‑GP Generator Protection Panel, GWPC‑LCU‑G Unit LCU Panel and GWPC‑EXC Excitation Control Panel.

The panel supports integration with plant SCADA and automation systems for telemetry, telesignalling and telecontrol. Depending on the project configuration, it supports:

RS-485/Modbus RTU
Ethernet/IEC 60870-5-104
Optional IEC 61850
4–20 mA analog inputs/outputs
Generator start/stop and synchronizing-point selection
Voltage, frequency-difference and synchronizing-parameter monitoring

Interfaces, protocols and signal configurations can be customized to meet project requirements

GWSC300-SCADA Hydropower Station Monitoring Interface

GWSC-HS Hydropower Station Computerized Monitoring and Control System

Desc

The GWSC-HS is a new-generation distributed intelligent monitoring platform suitable for conventional hydropower stations, ecological hydropower stations, diversion hydropower stations, and pumped-storage power stations. Fully compliant with international power industry standards and deeply integrated with professional hydropower automation control technologies, the system realizes integrated monitoring and automatic control of turbine governing, excitation regulation, synchronizing, relay protection, AC/DC power supply, gate control system, plant-wide oil-water-gas auxiliary systems, and switchgear bay-level measurement and control functions. It supports unattended or reduced-staff operation modes for hydropower stations.
Adopting an open modular architecture, the entire set of automation equipment forms a unified and standardized brand system, including station-level equipment, GWPC series control panels, GWPC300 series protection panels, GWPS AC/DC power supply systems, as well as distributed protection relays and intelligent meters for switchgears. All equipment features high compatibility and interoperability. With complete sequence control logic, intelligent regulation algorithms, fault early warning mechanisms and standardized dispatching interaction capability, the system effectively improves hydropower station operational safety and power generation efficiency, reduces on-site operation and maintenance costs, and supports the digital and intelligent upgrading of hydropower plants.
