Having a stable and reliable power system is vital for efficient and safe operations of oil and gas installations. The harmonics and power grid disturbances occur due to usage of adjustable motor drives and frequent start-stop operations, respectively. Excessive reactive power is another problem arising from motors. Therefore, the power quality issues should be carefully considered and compact, modular and robust solutions should be applied due to harsh and remote environment, the need of low space, and continuity of the operation. We offer complete solutions to full fill the exact needs of oil and gas industry considering all limitations and constraints. Our modular and robust designed STATCOM systems are the solution for reactive power compensation and can be used to minimize disturbances by dynamic voltage control mode. Specially designed line and load side harmonic filters for adjustable motor drives are the remedy for harmonic problems.
