This paper proposes a novel frequency adaptive cascaded synchronous reference frame-phase locked loop (FACSRF-PLL) based approach of load compensation for distribution static compensator (DSTATCOM). The non- linear and unbalanced load make the source current distorted. The CSRF-PLL can fine define fundamental angular frequency, amplitude & phase angle and positive sequence component. The FACSRF -PLL control approach provide switching pulses in a way to make source current balanced & sinusoidal and also improve power quality of system. Here FACSRF is act as a pre-filter for the PLL and improve performance under distorted grid conditions. The proposed FACSRF -PLL control approach is executed in MATLAB/ Simulink environment with various operating condition. The ability of the proposed approach has been related to the instantaneous PQ theory-based control technique.
