METHOD FOR REGULATING POWER OF COMPENSATION FILTER INSTALLATION IN RAILROAD TRACTION ENERGY SUPPLY SYSTEM

摘要

FIELD: electricity.SUBSTANCE: compensation filter installation (CFI) is switched on or off depending on values of measured actual displacement power factor tg?at hours of high daily loads in the electric mains and CFI is switched off at hours of low daily loads at generated reactive power: tg?.= 0. Unit for computation of total voltage harmonic factorat busbars of 110 (220)kV and units for computation of displacement power factor for load tg? and generated reactive power tg?calculateand tg?at switched off CFI at hours of high loads supposing that CFI is in switched on position. CFI is switched off in conditions ofand tg?? tg?, whereand tg?are permitted values. At switched off CFI at hours of low loads actual value ofis measured and tg?is calculated supposing that CFI is in switched on position. In conditions ofand tg?= 0 CFI is switched on.EFFECT: effective compensation of reactive power and reduced level of current and voltage harmonics.1 dwg
