Traditionally used static are compassers and fixed mechanical switched condensator groups are used to improve power quality in the transmission and distribution systems. In recent years, some power quality healing devices have been developed for reactive power compasion in energy systems. Flexible Alternative Stream Communication Systems (FACTS) devices are power quality improvement devices. One of these FACTS devices is the Statistical Synchron Companzator (STATCOM). STATCOM is a power-based power quality enhancement device and is used to improve power quality in energy systems. The voltage-controlled evaporator used in the STATCOM structure can be done multi-level as it can be done in the classical two levels. Control of the STATCOM device is usually carried out with fixed parameters PI controls. However, the desired control performance is not achieved due to nonlinear structures. In this study, an indirect flow control method was used based on the synchronous reference structure theory for the control of STATCOM. In this control method, the d and q axes are controlled with a strong structure of the Bully Logic Controller (BMD). The simulation work is done in Matlab/Simulink software. The classical two-level equator is compared with the comparison works performed using five-level equator structures.
