The water turbine is a key element in converting the kinetic energy of flowing water into mechanical energy. This energy conversion process forms the fundamental basis of electricity generation.

The efficiency of a water turbine depends on such factors as the design of the runner blades, water velocity and pressure, the hydraulic head of the water source, as well as overall operating conditions.

• The selection of a turbine depends on the specific site conditions (e.g. flow rate, head height, available installation space).
• When considering the purchase of a turbine, in addition to initial capital cost, such aspects as efficiency, reliability, and maintenance requirements should be taken into account.

We customize our turbines in accordance with your specific requirements. Producing the equipment, we usually take into account such parameters as water head, flow rate, voltage level, frequency, grid-connected or off-grid operation mode, and the degree of automation to develop an optimized solution.

Our company supplies turbines classified by their operating principles into impulse turbines and reaction turbines. Impulse turbines generate rotational motion by the impact of water jets on the turbine runner, while reaction turbines are driven by the reactive force produced as water flows over the blades.

Our reaction turbine stock includes:

• Mixed-flow (Francis) turbines
• Axial-flow (Kaplan) turbines
• Tubular (propeller) turbines.

The tubular turbine is a perfect choice for very low head and very high flow rates, offering large flow capacity, high specific efficiency, and the advantage of requiring no excavation.

Structurally, tubular turbines can be classified into:

• Spherical
• Pit-type
• Siphon-type
• “S” type

A Pelton wheel turbine is a type of impulse turbine, in which the water jet flows tangentially onto the runner buckets. The water in a Pelton turbine has a high velocity, and the turbine extracts energy by reducing the water jet velocity through impulse action.

Impulse turbines are primarily employed for high water head and low flow rate conditions.

In a turbine, the blades or buckets are strategically positioned to redirect the water flow, thereby altering its momentum. The change in water momentum generates a corresponding force that causes the rotor or turbine runner to rotate. A key factor in this process is the magnitude of the momentum change, as it directly affects the applied force. The greater the momentum change, the higher the force exerted, which enhances the energy conversion efficiency.

• Power generation: Water turbines are extensively employed in hydropower plants to convert the energy of flowing or falling water into electricity, providing a reliable and renewable energy source
• Industrial processes: Water supply mechanical power for various industrial applications such as milling, pumping, and driving machinery, enhancing operational efficiency and productivity
• Water supply and irrigation: Water turbines drive pumps in water supply systems and irrigation networks, facilitating the effective distribution of water for domestic and agricultural use
• Flood control and water resource management: Regulating the flow of rivers and reservoirs, hydraulic turbines play a crucial role in flood prevention and the management of water resources.

Tubular turbines are generally suitable for rivers with high flow rate, low heads ranging from 4 to 25 meters. Additionally, tubular turbines offer construction advantages such as simplified installation, reduced concrete use, and faster assembly.

The tubular turbine casing is fabricated from conventional steel, while the blades are made of stainless steel, providing corrosion resistance and a service life of over 30 years. The generator housing is made of steel and contains coils and magnetic poles internally.

Tubular turbines are the optimal choice for developing low-head, high-flow tidal and hydraulic energy. It features large flow capacity, high efficiency, and minimal excavation requirements.

After placing an order for our turbine units, we will provide you with a complete set of installation drawings. If needed, we will also assist and guide you through the installation process.

Pelton turbines are generally suitable for rivers with high head, typically ranging from 200m to 800m, and relatively low flow rates. In addition to their suitability, Pelton turbines offer practical benefits such as convenient construction, requiring less concrete, and allowing for quick installation, making them a cost-effective and efficient choice for high-head hydropower projects.

The efficiency of impulse turbines can reach up to 95%. For micro-hydropower plants, the maximum efficiency of Pelton turbines can reach approximately 90%.

The casing of a Francis turbine is typically made from conventional steel. The runner blades are made of stainless steel, which offers excellent corrosion resistance and ensures a long service life of over 30 years. The generator casing is also made of steel and contains internal components such as coils and magnetic poles essential for electricity generation.

Kaplan turbines have axial water flow both at the inlet and outlet, whereas Francis turbines have mixed-flow directions. Kaplan turbines feature smaller cross-sectional flow areas and operate at lower rotational speeds, which contrasts with the operating characteristics of Francis turbines.

The Francis turbine integrates features of both impulse and reaction turbines. It harnesses the kinetic energy of water through both the impact of the water striking the blades and the reaction force generated as water flows over and around the blades. This combination allows the Francis turbine to achieve enhanced power output and efficiency across a wide range of operating conditions.

Francis turbines are used in rivers with medium head, generally between 20m and 100m, and very large flow rates. They offer construction advantages such as reduced concrete usage and quick installation, which makes them the most efficient type of turbine available.

A Kaplan turbine is a propeller-type axial-flow turbine with adjustable blades, specifically designed for low-head, high-flow applications.

A Kaplan turbine consists of:

• Scroll casing, which directs water into the turbine while maintaining pressure
• Guide vane mechanism controlling the flow rate and water direction
• Draft tube, which converts kinetic energy into pressure energy
• Runner blades, which convert the water flow into rotational mechanical energy.

Water enters the scroll casing where pressure is maintained. It then passes through the guide vanes, which regulate flow and reduce turbulence. Next, the water reaches the runner blades, which adjust their pitch to optimize turbine performance. Finally, the water exits through the draft tube, where kinetic energy is converted into pressure energy. The rotation of the runner generates mechanical energy that can be converted to electricity.

Kaplan turbines are suitable for low-head, high-flow applications. They are usually applied in:

• Power generation
• Small-scale hydropower stations.

Large axial-flow turbines are specifically designed to achieve optimal performance at particular sites, offering long-term operational efficiency.

Their adjustable blades combined with an axial-flow design make them an ideal choice for environments characterized by low water levels but high flow rates, ensuring optimal performance in such settings.

There are various types of hydropower technologies, but they all harness the energy of flowing water to generate electricity. For example, in penstock projects, small-scale turbines are installed within existing infrastructure such as irrigation canals. As water flows through the turbine, it spins the blades connected to a shaft, which in turn drives a generator to produce electricity. This electricity is then transmitted via power lines to homes and businesses.

Small-scale hydropower projects typically have capacities of 10 MW or less. They often use run-of-river designs, making them one of the most environmentally friendly energy conversion solutions because they cause minimal disruption to river flow. The threshold separating small and large hydropower varies by country, generally ranging from 10 to 50 MW.

The advantages of hydropower projects are the following:

• Contributes to mitigating global warming by reducing carbon emissions
• Supports power generation while providing water resource management benefits
• Reduces downstream flood hazards by controlling water discharge during heavy rainfall or snowmelt.

Hydropower is a capital-intensive form of power generation based on renewable energy that does not consume any fuel. Its operational and maintenance costs are relatively low, leading to minimal long-term expenses. Compared to coal and gas-fired power plants, hydropower generally offers lower generation costs.

Additionally, hydropower helps reduce financial losses caused by frequency fluctuations in the power grid. Since it does not rely on fossil fuels, hydropower is not subject to inflationary pressures, making it a more stable and reliable energy source over time.

The size of hydropower units depends on the flow rate and the available water head at a specific project site, causing unit sizes to vary by location. Additionally, generator size also depends on seasonal variations in river flow and water availability throughout the year.

Hydropower plants are considered an economical option for meeting peak grid loads due to their unique ability for rapid start-up and shutdown.

Yes, definitely! We offer customized mini hydropower solutions tailored to the specific needs of remote rural regions and agricultural irrigation applications.

The size of a substation is determined by several factors:

• Voltage level, usually indicated by the rated high-voltage side of transformers (e.g., 35 KV, 66 KV, 110 KV, 132 KV, 220 KV, 330 KV, 500 KV, 750 KV, or even up to 1000 KV).
• Total transformer capacity, which refers to the combined capacity of all the main transformers within the substation.
• Number of outgoing feeders at each voltage level, representing the distribution circuits from the substation.

The primary electrical equipment in power plants and substations includes:

Key components include:

• Transformers
• Circuit breakers and switchgear
• Busbar control and protection devices
• Supporting structures and foundations.

• Transmission substations (step up the voltage to facilitate long-distance power transmission through the grid)
• Distribution substations (step down the voltage to levels suitable for final distribution to consumers)
• Collector substations (collect electrical power from various sources or multiple power plants)
• Switching substations (help control the flow of current and enable switching between different power sources to maintain system reliability).

The gantry is a critical structural component in substations, designed to support and organize overhead conductors. It ensures that electrical lines maintain proper clearance from each other, preventing clashes and electrical faults.

Substations play a vital role in regulating voltage and distributing electrical power, which helps reduce outages and ensures seamless power delivery to consumers.

Substations also incorporate advanced grid resilience technologies that enable the system to withstand extreme weather conditions. This enhanced resilience reduces downtime, prevents economic losses, and helps safeguard public safety.

The benefits of substations in power distribution are the following:

• Efficient power transmission and distribution: Substations ensure that voltage levels are optimized for both long-distance transmission
• Voltage regulation and control: Substations maintain stable voltage levels across the entire power grid, helping to prevent fluctuations
• Grid stability: By regulating current flow and isolating faults, substations enhance the overall reliability of the electrical system
• Minimized transmission losses: Through appropriate voltage transformation, substations reduce energy losses during transmission
