Hydroelectric Plant Retrofitting and Irrigation Systems

Retrofitting of hydroelectric power plants (HPPs)

This category includes components that play an essential role in converting water energy into electricity:

Hydraulic turbines: Replacement or retrofit
Electric generators: Replacement or retrofit
Transformers and switching equipment:
- Replacement of power transformers with more efficient models
- Modernization of medium and high voltage cells
- Introduction of modern protection systems against overvoltages and internal faults

To increase the efficiency of operation and monitoring, the power plants are equipped with:

SCADA (Supervisory Control and Data Acquisition) systems for real-time monitoring and control of operating parameters
Sensors and equipment for automatic detection and reporting of faults
Protection and automatic regulation systems to prevent breakdowns and optimize energy production
Automation of the processes of starting, stopping and regulating turbines and generators

Repair or replacement of hydraulic equipment (dams, discharge valves, retention equipment)
Rehabilitation of water intakes and supply channels to reduce water losses

Modernization of exhaust, lubrication, cooling and ventilation installations for more efficient operation
Implementation of water filtration and purification systems to protect equipment from impurities

Replacement or rehabilitation of transformers to ensure stable power supply to pumping equipment
Modernization of distribution networks (cables, electrical panels, connections) to reduce energy losses and prevent overloads
Installation of backup generators to ensure continuity of operation in case of failure

Replacement of old electric motors with high-efficiency motors to reduce energy consumption
Installation of inverters frequency (VFD – Variable Frequency Drives) to regulate the flow and pressure of the pumps according to needs
Installation of soft-starters to reduce electrical shocks when starting the motors and extend their lifespan
Automation of the operation of the pumps through sensors and controllers to optimize energy consumption
Implementation of water filtration and purification systems to protect the equipment from impurities
Modernization of exhaust, cooling and ventilation installations for more efficient operation
Unclogging of the suction basins of the pumping units
Rehabilitation/replacement of lifting elements.
Rehabilitation of the interior and exterior architecture of the building.

Installation of PLCs (Programmable Logic Controllers) for automated irrigation control
Integration of SCADA systems for remote monitoring and management of energy consumption and equipment operation
Humidity, flow and pressure sensors that automatically adjust the start and stop of the irrigation system
Remote management and control via the internet or mobile applications to optimize water and energy consumption
Unclogging of irrigation channels and their waterproofing by applying Concrete and Geomembrane on existing surfaces.
Replacement of flow control/monitoring elements: flow meters, weirs, bollards.

Use of renewable energy by installing photovoltaic panels to power pumping stations
Implementation of energy storage systems to reduce dependence on the electrical grid
Optimization of lighting systems at pumping stations by using low-consumption LEDs
