چکیده
Power quality (PQ) has become a key problem of urban power grid recently. Improving power quality is a technical problem being concerned by both power supply companies and the consumers. Shenzhen power grid, as a typical urban power grid, is exemplified in this paper. Through researches, typical PQ issues of a key region in urban power grid are discussed. Industrial feasibility study is carried out on medium-voltage high-power comprehensive treatment device for solving voltage sags problems in regional power grids. Based on the statistical analysis of PQ monitoring data of Shenzhen power grid in the recent three years, a medium-voltage high-power PQ regulator is designed. Simulation experiments are carried out using PSCAD simulation software, and these experiments show that the device can effectively solve the PQ issues of regional power grids. This design scheme is exploratory and instructive for improving regional power quality in urban power grid.

متن کاملFast Transient Hybrid Neuro Fuzzy Controller for STATCOM During Unbalanced Voltage Sags
A static synchronous compensator (STATCOM) is generally used to regulate voltage and improve transient stability in transmission and distribution networks. This is achieved by controlling reactive power exchange between STATCOM and the grid. Unbalanced sags are the most common type of voltage sags in distribution networks. A static synchronous compensator (STATCOM) is generally used to maintain...
متن کاملA new technique to improve AC coil contactor switching in presence of voltage sags
Total complaints related to voltage sags are about 80 % of all the complaints due to power quality transients. AC Contactors are designed to disconnect the load or circuit they control when the main power supply is intentionally interrupted. The sensitivity of AC coil contactors to the applied voltage is thus a potentially weak link in industrial processes. This paper shows the test results obt...
