Gwind Floating Gyro-Stabilized VAWT

Posted on 15 aprilie 2015 by admin

Un proiect VAWT Offshore este cel propus de Gwind care demonstreaza avantajul centrului de greutate pozitionat la o distanta mica fata de nivelul marii.

Prototipul foloseste turbine eoliene verticale realizate de UGE.

VAWT Offshore

Răspunde

In acest moment turbinele VAWT prezinta un interes deosebit pentru utilizarea offshore datorita a trei mari avantaje :

centru de greutate pozitionat mai jos decat la HAWT (costuri mici pentru structura aflata sub nivelul marii )
greutatea palei nu limiteza dimensiunea acesteia
performantele turbinei nu sunt afectate de schimbarile directiei vantului

vawthawt

Proiectele lansate in Europa sunt : Nenuphar , Aerogenerator SpinFloat si DeepWind.

Prototipul turbinei DeepWind demonstreaza avantajul centrului de greutate amplasat mai jos decat la HAWT

Conceptul Aerogenerator arata posibilitatea construirii unei turbine VAWT gigant

Proiectul Nenuphar este cel mai avansat cu un buget alocat imens.

Hrotor ?

Posted on 7 aprilie 2015 by admin

Răspunde

Curios dar un Hrotor fara un profil aerodinamic poate genera putere. In simulare soliditatea este egala cu 1. Randamentul turbinei in simulare este de 0.12

https://www.youtube.com/watch?v=H6dPNKastO8#t=40

Privind superfial putem spune ca componenta lift a turbinelor Thies, Lenz2, Crotor este asigurat de acest profil plat .

cp(lenz2)=cp(savonius)+cp (flat) adica 0.3=0.18+0.12

Acest tip de rotor ma duce cu gandul la rotorul Miller

Determinarea turatie turbina VAWT

Posted on 28 martie 2015 by admin

Răspunde

Turatie turbina : Una din metode este masurarea frecventei curentului alternativ produs de generator. In functie de numarul magnetilor de pe disc si a numarului de impulsuri contorizate in unitatea de timp se poate determina turatia turbinei.

turatie turbina : Codul pentru determinare turatie cu ajutorul Arduino

for(int i=0;i<500;i++)
  {
    sample1+=analogRead(A1);  //se citeste tensiunea
    sample2+=analogRead(A2); //se citeste curentul
    
    AC = digitalRead(2); //

   // Se contorizeaza trecerea prin "0"
   if ((AC == LOW) && (AC != lastAC ))
   {      
      sample3++;     
    }
    
    lastAC= digitalRead(2);
    delay(5);
  }
  sample1=sample1/500; // se mediaza tensiunea
  sample2=sample2/500; // se mediaza curentul
  turatie=sample3*60/2.5/8; // se calculeaza turatia in functie de numarul de magneti

for(int i=0;i<500;i++)

{

sample1+=analogRead(A1); //se citeste tensiunea

sample2+=analogRead(A2); //se citeste curentul

AC = digitalRead(2); //

// Se contorizeaza trecerea prin "0"

Afisare live a parametrilor VAWT

Posted on 16 martie 2015 by admin

VAWT online . Pentru afisarea live a parametrilor furnizati de senzori prin intermediul Arduino si inregistrati intr-o baza de date SQL se foloseste formatul de date „JSON” si Google Gauge.

VAWT online codul necesar :

1.” data.php” pentru pentru interogarea bazei de date si trimitere a datelor in format „JSON”

<?php

// Conectare la baza de date
    mysql_connect("Localhost", "user", "parola") or die(mysql_error()); 
    mysql_select_db("nume baza de date") or die(mysql_error()); 
    
$result = mysql_query("SELECT * FROM tempLog ORDER BY timeStamp DESC LIMIT 1") or die (mysql_error());
   $row = mysql_fetch_assoc($result);
    

echo json_encode($row);
exit;


?>

<?php

// Conectare la baza de date

mysql_connect("Localhost", "user", "parola") or die(mysql_error());

mysql_select_db("nume baza de date") or die(mysql_error());

$result = mysql_query("SELECT * FROM tempLog ORDER BY timeStamp DESC LIMIT 1") or die (mysql_error());

$row = mysql_fetch_assoc($result);

echo json_encode($row);

exit;

2. „index.html” pentru afisare folosind Google Gauge:

Pentru a inregistra parametrii de functionare a unei turbine eoliene intr-o baza de date SQL se poate folosi solutia compusa din :

        $putere1=$_POST["putere1"];
                    

    $query = "INSERT INTO `tempLog` (`temperature`, `humidity`, `curent`, `tensiune`, `putere`) 
        VALUES ('".$temp1."','".$hum1."','".$curent1."','".$tensiune1."','".$putere1."')"; 
    
    mysql_query($query);
    mysql_close;

      

    header("Location: index.php");

?>

<?php

// se conecteaza la baza de date

mysql_connect("Localhost", "user", "parola") or die(mysql_error());

mysql_select_db("nume baza de date") or die(mysql_error());

$temp1=$_POST["temp1"];

$hum1=$_POST["hum1"];

$curent1=$_POST["curent1"];

$tensiune1=$_POST["tensiune1"];

$putere1=$_POST["putere1"];

$query = "INSERT INTO `tempLog` (`temperature`, `humidity`, `curent`, `tensiune`, `putere`)
