| Summary: | To solve the prominent power quality problems such as negative sequence component, reactive power, and harmonics in traction power systems, it proposed an unified power manipulate supply (UPMS) which features high cost-efficiency and fits the power supplying and operation characteristic of traction power system well. In topology, two parts are included, one is active part, which mainly responsible for active power delivery and dynamical reactive power compensation; and the other is passive part, which is used for filtering low order harmonics and offering reactive power. By means of cooperation of those two parts, the capacity of active part can be effectively reduced, leading to whole system cost-efficiency. The measured results of a real UPMS in a substation of Hunan province indicate that UPMS is in good condition, and the primary power factor can be effectively improved to be above 0.95, the negative sequence voltage unbalance ratio can be suppressed to be lower than 2%, and the harmonics can be so much filtered that the related harmonics requirements can be satisfied. |
