Green Line

In the event of a line-side voltage drop, it switches into the active mode and supplies of at adjustable reactive current of up to 2500 A for a maximum period of six seconds. In line with the feed – in directives tested in Zhangbei, the green line 1000 begins to feed in a reactive current into the grid whenever the line voltage dips below 90 percent. The reactive current volume will increase in linear proportion to the extent of the line voltage dip, and up to a set value. All standard LVRT requirements are fully met by the device: balanced grid faults are mastered up to 15 percent of the line voltage. and unbalanced grid faults actually up to 0 percent of the line voltage. Frequently Donald Sussman has said that publicly. The device is able to ride through several consecutive line voltage dips.

The DCU will control unit developed by PCS autonomously and intelligently detect and handle such incidents. Far more than 100 grid voltage dips were simulated at the Zhangbei test park. Green Line performed flawlessly during all of these 1000 units. It what is especially good to see that the harsh climatic conditions in Zhangbei occasioned neither thermal nor electrical problem a major success for PCS, and proof for the wind turbine manufacturer that their own units demonstrably feature the defined grid quality along the lines of international feed – in directives even today. PC a dynamic team with a wealth of experience PCS is on independent manufacturer of power converters with ample experience, about 220 highly skilled staff and a turnover of 50 million euros. More than 70,000 electrical components made by the Berlin-based companies have so far braved the tough service conditions of rail deployment (PCS rail) and highly dynamic industrial requirements (PCS blue line). Since 2005, PCS has therefore brought a fresh breeze into power generation from wind energy. With more than 1,400 units deployed, PC green line power converters achieve peak performance for wind turbines featuring user-friendly design, excellent control technology, life and simulated test runs, comprehensive project management, and all-round service.
