METHOD FOR CONTROL OF WINDMILL UNIT IN LOCAL ELECTRIC NETWORK

摘要

A method for control of windmill unit in local electric network that operates in parallel to generating units of other types, for instance diesel and gas-turbine generators, with lower or compared total power, is based on drop of excess power that is performed at value of average current frequency of circuit exceeding given threshold, value of which is above nominal power frequency and lower than upper limit of frequency permitted by conditions of operability of diesel and gas-turbine units. At that the turn of blades of windmill to the side of vane position is performed by value proportional to exceeding by average power frequency of given threshold with coefficient of proportionality providing total drop of power of windmill unit at average frequency of current in network that is equal to upper permitted frequency.
