Phase Modifier Cooling System

With the rapid development of HVDC, the large-scale development of clean energy and the emergence of large scale power receiving areas, the problem of dynamic reactive power reserve and voltage support of HVDC terminals is becoming more and more serious.The phase modifier has strong bidirectional reactive power regulation capability. When serious voltage drop fault occurs, it can provide reactive power in short time and reduce the effect of frequency locking on the regional power grid when the HVDC transmission is blocked.As an important part of the phase modifier, the cooling system of the phase modifier is the prerequisite and guarantee for the stable operation of the phase modifier .
