Control Enercon Wind Turbines

This package uses the gopcxmlda package to interact via OPC XML DA with an Enercon SCADA PC and exposes functions to control Enercon Wind Turbines.

Functions

The following Functions are implemented:

• Start
• Stop
• Reset
• RbhOn
• RbhAutoOff
• RbhStandard
• ControlAndRbh
• Turbines
• ParkNoMatch

Roadmap:

• No new features are planned at the moment. Feel free to open an issue if you have a feature request or create a pull request if you want to contribute.

Basic Procedure

Basic usage is as follows:

package main
import (
    "github.com/dernate/energontrol"
)

func main() {
	_url, _ := url.Parse("http://your-opc-server:port/DA")
	s := Server{
	    _url,
		"en-US", 
		10,
	}
}

Start(Context, Server, UserId, PlantNo...)

Start one or more turbines.

Example:

UserId := 1234
PlantNo := []uint8{2, 4}
started, errList := Start(context.Background(), Server, UserId, PlantNo...)

Stop(Context, Server, UserId, FullStop, ForceExplicitCommand, PlantNo...)

Stop one or more turbines. FullStop can be false for 60° stop or true for 90° Stop. If ForceExplicitCommand is false, then any stop status that is already present is accepted. (For example: Requested status Stop60, but the plant is already at Stop90, then it is not stopped at Stop60, but Stop90 is accepted) If ForceExplicitCommand is true, then the plant is stopped at the requested status, even if the plant is in a similar status.

Example:

UserId := 1234
PlantNo := []uint8{2, 4}
stopped, errList := Stop(context.Background(), Server, UserId, true, true, PlantNo...)

Reset(Context, Server, UserId, PlantNo..)

Reset one or more turbines.

Example:

UserId := 1234
PlantNo := []uint8{2, 4}
resetted, errList := Reset(context.Background(), Server, UserId, PlantNo...)

RbhOn(Context, Server, UserId, PlantNo...)

Set the Rotor Blade Heating to "Manual On".

Example:

UserId := 1234
PlantNo := []uint8{2, 4}
rbhOn, errList := RbhOn(context.Background(), Server, UserId, PlantNo...)

RbhAutoOff(Context, Server, UserId, PlantNo...)

Set the Rotor Blade Heating to "Auto Off" (Supress Automatic -> Off).

Example:

UserId := 1234
PlantNo := []uint8{2, 4}
rbhAutoOff, errList := RbhAutoOff(context.Background(), Server, UserId, PlantNo...)

RbhStandard(Context, Server, UserId, PlantNo...)

Set the Rotor Blade Heating to "Standard". If automatic heating is allowed, the automatic takes control.

Example:

UserId := 1234
PlantNo := []uint8{2, 4}
rbhStandard, errList := RbhStandard(context.Background(), Server, UserId, PlantNo...)

ControlAndRbh(Context, Server, UserId, Values, PlantNo...)

Set Ctrl and Rbh value for one plant at once. The CtrlValue and RbhValue are the numbers, which will be set in the OPC. See constants.go for the possible values.

Example:

UserId := 1234
Values := ControlAndRbhValue{
		SetCtrlValue: true,
		CtrlValue:    1,
		SetRbhValue:  true,
		RbhValue:     2,
	}
PlantNo := []uint8{2, 4}
controlled, errList := ControlAndRbh(context.Background(), Server, UserId, Values, PlantNo...)

Turbines(Context, Server)

Get a list of turbines and which controls are available for each turbine.

Example:

turbines, err := Turbines(context.Background(), Server)

ParkNoMatch(Context, Server, ParkNo, checkAvailable)

Read the Park Number from the Server and compare it with the provided ParkNo. If checkAvailable is true, the function also checks if the Server is running.

Example:

match, err := ParkNoMatch(context.Background(), Server, 1234, false)

Important:

Wind turbines are critical infrastructure! It is important to be particularly careful when interacting with them and only carry out tests in suitable test environments. I assume no liability for any consequences of using this source code, use at your own risk!
