WIND POWER PLANT OF
А NEW ТУРЕ (WPPNT)
Wind power plant of а new type (WPPNT) — Exclusive product in the wind energy market that has а number of undenible advantages over other products.
WPPNT CONCEPT
The WPPNT manufacturing technology implies the production of wind turbines from composite components using the most advanced lightweight and durable materials.
- Durability
- Reliability
- Innovative development
- Self-sufficiency
- Longevity
WPPNT will make our planet cleaner and help save it from global warming. WPPNT is an invention that utilizes the latest scientific achievements and knowledge in the field of aerodynamics. WPPNT converts the kinetic energy of the wind into mechanical energy used to rotate a generator. Its main purpose is to generate electricity.
By harnessing the power of the wind, the WPPNT allows the generation of electricity without any harm to the environment. WPPNT design begins to work at air flow speed of 5-7 meters per second and get a significant effect on the conversion of wind energy into the cheapest electrical energy.
Novator-78 LLC has been developing and creating WPPNT for five years. Our designers have managed to design a wild turbine, the use of which provides efficiency many times higher than that of other installations while maintaining a minimum cost of WPPNT. The higher efficiency of WPPNT compared to classical three-bladed wind turbines has been repeatedly confirmed by tests in natural conditions.
We have developed a method of molding of WPPNT parts by vacuum infusion, at such molding parts are obtained as light and strong as possible, do not succumb to corrosion and do not accumulate fatigue loads. Tests on strength of composite parts prove that at given overall dimensions WPPNT will have a multiple safety margin and service life not less than 40 years.
DESIGN FEATURES
lf we compare WPPNT and а classical three-bladed wind power plant of the same capacity, then three times less materials bу weight and volume are needed to create WPPNT. There are no technically complicated devices such as gearbox, gearbox unwinding mechanism,blаdе angle changer, tower vibration damper, all this reduces the cost of wind turbine production by 3 times, reduces maintenance costs and makes the generated electricity three times cheaper;
CASING WPPNT
There are two inlet ducts in the casing, so the air flow impacts the rotor from two sides and at different angles, doubling the power of the WPPNT;
INLET DUCTS
The turbine inlet ducts are smoothly curved and narrowed towards the rotor, which increases the air flow velocity and rotor speed by three times, making it possible to transfer rotational energy from the rotor to the generator without using а gearbox;
PROFILE ROTOR BLADES
The profile of the rotor blades is concave-convex, which, when streamlined by the air flow, makes it possible to obtain а large lifting force, thus increasing the speed аnd torque of the rotor;
SOUND INSULATION
When working WPPNT does not create noise and vibrations, WPPNT саn bе installed on residential houses, sea ships and yachts;
INLET DUCTS
The longer of the inlet ducts passes into the outlet duct, which creates an ejection effect and prevents the air flow from slowing down and the rotor speed from decreasing;
WPPNT MODULES
WPPNT consists of several modules, the number and size of which differ depending on the power. Dimensions of one such module do not exceed the standard permissible norms for transportation of cargo by heavy-duty vehicles (12000 x 3000 x 2500). Thus, transportation of WPPNT to the place of installation does not require special transport, reducing the cost of transportation and installation.
The design of the WPPNT allows the installation of the generator and auxiliary equipment under the turbine оп the ground, which facilitates the installation, connection to the power grid and further maintenance of the WPPNT and, therefore, saves additional costs. WPPNT is designed for 40 years of operation without maintenance and replacement of main units and mechanisms. WPPNT operates in automatic mode and do not require human intervention.
Тablе of power output of WPPNT (rotor height 15m) at different wind speeds
| Wind speed m/s | WPPNT Power Class 6M |

| 1М | 450 KW | 2,5 m |
| 2М | 900 KW | 5 m |
| 3М | 1350 KW | 7,5 m |
| 4М | 1800 KW | 10 m |
| 5М | 2250 KW | 12,5 m |
| 6М | 2700 KW | 15 m |
* The class name encodes the number of standard modules required to install а turbine of а certain capacity, e.g: 1M - one standard module is required to install а 450 КW turbine.
** WPPNT capacities are based оп а wind speed of 15 m/s.

WPPNT
These two wind turbine generators of equal capacity, at the same wind speed, produce the same
amount of electricity.
Let’s compare the technical characteristics of a three-bladed wind plant
(3-BWPP) and a new type of wind farm (WPPNT).
| Technical characteristics | 3-BWPP (3 MW) | WPPNT (3 MW) |
|---|---|---|
| Tower height (m) | 100 | 30 |
| Rotor diameter (m) | 80 | 4; rotor height 15 |
| Rotor speed, at wind 10m/s (rpm) | 5 | 145 |
| Efficiency | 18% | >50% |
| Payback | Impossible (Funds to be raised: state subsides. State renewable energy projects) | ~3 years |
| Generator | Located at a height of 60 meters (difficulty in maintenance and emergency repair) | On the ground (convenient and economical to maintain) |
| Method of starting operation (rotation) | Requires external source to start rotation | Starts operation by wind (self-propulsion) |
| Quantity of materials used in manufacturing | Norm | 4 times less |
| Rotation width (m) | 80 | 15 |
| Total mass of the structure (t) | 210 | 70 |
| Service life of bearing (years) | Up to 3 | Up to 10 |
| Presence of gearbox | Yes | No |
| Presence of gearbox unwinding mechanism | Yes | No |
| Presence of a mechanism for changing the blade angle | Yes | No |
| Presence of a vibration damper for the upper part of the tower | Yes | No |
All the above technical data make it possibe to reduce the production cost of WPPNT compared to 3-BWPP designs bу 3 times and, accordingly, the cost of the received electricity. WPPNT саn bе installed оn the roofs of residential buildings, as it does not create noise, vibrations and does not kill birds.
main competitor
The main competitors of WPPNT are classical three-blade wind power plants (3-BWPPs). Electricity from WPPNT is more expensive than electricity from oil, gas, coal, uranium and hydroelectric power plants. The world market shows that WPPNT are not profitable and are subsidized by the government.
Our WPPNT plant makes electricity cheaper and consumers' electricity costs lower.
Consumers need cheap and environmentally friendly electricity. Our innovative approach to the methods of obtaining "green energy" and experimental design solutions of engineers of our company "Novator-78" allows us to achieve maximum efficiency from the use of wind turbines WPPNT.
PRODUCTION IN ST. PETERSBURG
Our new type wind power plant WPPNT allows the production of up to 48 units per year with a capacity of 3MW.
