Realtime DSP grid measurement module - Surveillance of 3 currents and 3 voltages - New, improved algorithms for precise, fast and reliable grid measurements - Calculation of all grid data - Measures grid quality data - Supports FRT/LVRT - Supplies data for machine control - Supplies data for production statistics - Intelligent thermal control - Configurable measuring modes to present Power, Energy and Powerfactor The WP4x00 MK ll Control Concept The WP-Line 151 MK ll Grid Measurement module is part of the WP4x00 MK ll Control Concept which has been specially designed to control large wind turbines - on- and offshore. The WP4x00 MK ll Control Concept ensures optimal operation, high security, and advanced data collection. The concept typically consists of a power supply/backbone module, a WP4x00 MK ll controller, a grid measurement module as well as an analog/digital I/O module dependent on the specific configuration task. The WP4x00 MK ll Control Concept makes it possible to have redundant solutions. The concept is constructed as a plug-andplay system with automatic module detection and error reporting. Advantages of the WP4x00 MK ll Control Concept: ? Corrosion robust construction ? Robust WP-Line interconnection ? Fast and easy DIN-rail mounting ? Automatic node assignment of WP-Line modules ? Simplified module status indication ? Supports removable LED matrix display ? Service-friendly The WP-Line 151 MK ll The WP-Line 151 MK ll module has three voltage and three current analog inputs. The module is powered from the WPLine BUS. The WP4x00 MK ll controller can automatically update the programs via the network. The communication to the WP4x00 MK ll controller is event-based, which means that only changed values are transmitted via the network. Analog part is based on 16bit precision ADC. The WP-Line 151 MK ll module performs three basic functions: ? Calculates main grid parameters ? Calculates grid quality parameters ? Provides WP4x00 MK ll controller with these data Main grid parameters like voltage, current, active and reactive powers, etc. are used by WP4x00 control application for turbine overall control. Calculation of main grid parameters by precise and reliable DSP algorithms has the following features: ? Frequency calculation algorithm assures measurement accuracy 0.01 Hz and higher ? Voltage and currents are calculated using FFT algorithms ? Powers and energies are measured according to IEC 61400-21 standard ? Precise DSP algorithms and high update rate make support for FRT/LVRT
