APPLICATION FIELDS
APPLICATION FIELDS
Wind power plant
The wind is uncontrollable, so it results in frequent fluctuation of reactive power, MCR typed SVC can realize fast and dynamic reactive power compensation and stabilize power grid voltage.
Long Distance Power Transmission
The SVC of TCR cannot be directly installed in transmission lines with over 35KV, but the SVC of MCR can be installed in extra-high voltage and ultra-high voltage transmission lines directly and it has no need of action of switching.
Secondary Substation (66kV to 110 kV)
In the regional power grid, the stepped switching capacitor banks are used to compensate the system reactive power and increase the power factor but they are only able to provide the capacitive reactive power, and unable to realize rapid and accurate adjustment according to the load variation. So sometimes they provide excessive reactive power than the actual desired reactive power, which will result in over voltage of the bus bar and damage the electric equipment and destroy system stability. Our SVC is able to compensate with capacitive and inductive reactive power rapidly and accurately.
Electric Railway Traction Substation
The electric locomotive is powered by single phase power system, which not only causes serious three-phase unbalance and low power factor but also generates negative-sequence currents. Currently the only way to solve the problem is to install SVC system at appropriate locations along the railway. The SVC is able to balance the three-phase by means of single-phase compensating and to increase the power factor through filter capacitor.
The optional operating software has visual system circuit displaying and operating interface, it can display three-phase reactive power, three-phase active power, current, power factor, working state of SVC with MCR type, desired power factor and set value, which is convenient for users to realize remote monitoring and communication regulation.
