WIND TURBINE LOAD OPTIMIZATION CONTROL STRATEGY BASED ON LIDAR FEED-FORWARD CONTROL FOR PRIMARY FREQUENCY MODULATION PROCESS WITH PITCH ANGLE RESERVATION

Wind Turbine Load Optimization Control Strategy Based on LIDAR Feed-Forward Control for Primary Frequency Modulation Process with Pitch Angle Reservation

Because wind power is connected to the grid on a large scale, frequency fluctuation in the power grid, which is defined as a system safety risk to the power grid, occurs from time to time.According to the grid code rules of China, wind turbines are required to be equipped with primary frequency modulation or inertia response control capability, whi

The impacts of ground-based logging equipment on forest soil

Soil properties can be affected by heavy equipment used for skidding but these impacts vary greatly with site conditions and operational practices.We assessed Baking Pans the effects of ground-based skidding on site disturbance and soil physical properties.We also tested the effects of skid trail slope and traffic frequency on soil compaction, tota
