WP4060 Connection Module

The WP4060 Connection Module is used for soft connection of wind turbine generators to the grid.

Features

• Continuous safety test of correct thyristor sequence.
• Surveillance of too high temperature on thyristors with bimetal sensor.
• Available for 1 or 2 generator systems.
• Possibility of throughout logging of all relevant data.
• Download of log data through the IC/WP controllers.
• Designed for easy mounting.
• Pressure sensitive touch screen; responds to finger, gloved hand or pen.

Cos.phi Circuit and Functionality

The Cos.phi circuit of the WP4060 ensures an effective current control before, during and after the synchronous point. Mita-Teknik has also developed a WP4060 unit for developing purposes. This unit has a built-in RAM for storing parameter settings.

Thyristor Control

The connection current is chosen as a parameter on the control unit. The thyristors can be connected during low production. The parameters for the opening of the thyristors are set on the control unit.

Built-in Circuits and Safety Features

The WP4060 has a built-in DELTA PHI circuit, which measures whether the generator receives or transmits power. The module has a built-in phase detecting circuit, which prevents connection if the phase sequence is incorrect. Soft connection of generators with either ?6-wire cable? or ?3-wire cable connection?. With real-time autodetector.

Compatibility and Patent

The WP4060 can replace our former connection module WP2060, if the DELTA PHI function of the WP4060 is deactivated. Mita-Teknik has been granted patent on the WP4060 module.
