In SMES coils for power system control, the use of low loss type strand cables are necessary to reduce aclosses accompanied with fluctuated magnetic fields; however, it brings some difficulties of high cost and low mechanical strength of the coil. To solve the above problems,the shielding coil system, which is composed of a superconducting main coil and a normal shieldingcoil connected in parallel, were proposed. In this system, the fluctuated current at energy input and output is diverted to the shielding coil and only the constant current flows in the main superconducting coil. For the shielding condition, it is necessary to compensate the voltage descent in the normal shielding coil. To confirm the operation of compensation power supply, we are planning to experiment of a solenoidal shielding coil system and now manufacture the experimental device.
