Analysis of fan distance and wake in wind farm

The characteristics of the wind farm have determined the location of the wind farm construction. The distance between the wind turbines must be greater than 500m. The influence of the wake of the wind turbine must also be considered. Therefore, the wind farm generally occupies a large area, has a wide distribution range, and the location is arranged. It needs to be determined based on factors such as wind measurement results and wind resource evaluation. Considering that all wind turbines may need to travel dozens of kilometers, maintenance is difficult, etc., the networking mode of wind farm communication requires high reliability, and the fiber ring network mode is generally considered. The power line of the power cable can be used to form a plurality of ring networks to complete the fiber-optic communication of the wind farm, and each fan acts as a communication node. The central monitoring system of the wind farm is generally configured in the monitoring room of the wind farm booster station and also serves as a node.

Wind farm central monitoring system topology reference substation dispatching automation system, under the premise of ensuring high reliability, the minimum configuration of wind farm central monitoring system can be completed by two computers, or can be completed by several computers according to functional division, equipment includes data Acquisition server, database server, monitoring workstation, report workstation, printer, switch, etc.

The data acquisition server completes the collection of data of each fan, wind tower and related substation, and at the same time completes the function of the monitoring system to issue the fan control command, generally uses the common OPC communication protocol to communicate; the database server completes the analysis, statistics and processing of the collected data. And stored in a relational database, the database generally uses a large relational database SQLSERVER or oracle; the monitoring workstation completes the human-computer interaction display of the fan and its components, the display of the fan operation and alarm information, and the operation of the operation command; The workstation completes the production and release of the wind farm report.

2 Ton Electric Stacker

1. Multifunctional handle
The multifunctional handle is imported from Germany. It has integrated control functions including a speed button, horn button, emergency reversing button and lifting button. The handle has an emergency reversing button which can effectively protect the operators from being hurt in accident involving falling items. The handle can realize braking both in vertical and horizontal position. The human-machine design is quite safe and the operation is more comfortable.

2. Strong power
This stacker adopts high efficiency motor which can be precisely controlled and the output power is strong. The turning control can be optionally equipped with EPS. It can help the driver with turning by using electronic control device to produce auxiliary power of relative level and direction according to the torque signal and speed signal. So the operation of the driver can be more convenient and precise and the movement can be more stable and reliable.

3.Superior gradeability
The powerful motor and 5 wheel stacker structure can provide superior stability and gradeability, so that the truck can have sufficient gradeability when it is fully loaded.

4. Buffered pedal
The foldable pedal can save space when the stacker is not in use. It can also effectively protect the drivers from being effected by the bumping and give feedback to the driver with the road condition.

5. Dual balance wheel device
This stacker is equipped with a dual balance wheel so that it can overcome roadblocks easier and the running can be more stable.

6. Emergency power-off switch
The power can be rapidly cut off in emergency to ensure safety.


Electric Stacker, or walkie stacker, is an industrial device for loading and lifting pallets on a shelf at high level. As an ideal choice to operate in narrow space of warehouse, it can be widely used in petroleum, chemical, pharmaceutical, textile, pigment, coal and other industries, as well as ports, railways, freight yards, warehouses.


Compared with the traditional manual stacking, Zowell full electric stacker maintains great advantages in safety, efficiency and cost. In addition to durability and accuracy both outside and inside, Zowell XE electric stackers are also equipped with mast with clear view, double speed and lateral vertical moving switch, which are valuable when working in limited space.

The standard load capacity of XE series ranges from 1 ton to 2 tons, two driving modes: walking and standing driving. If you need bigger capacity or other customized options such as rod, low mast, grabbling frame, please contact us so that we can provide you best solution with professional knowledge.
