| 总结: | In the early days of electrical usage, standard electric services, along with its associated short comings, was usually adequate for operating most electrical equipment. Digital electronic devices, specifically digital clocks and other microprocessor-controlled devices (industrial controllers and personal computer), began appearing in the mid-to-late 1970's. As those devices became more widely used, it became clear that the old standards of electric power were not adequate for their reliable operation[l]. Their connection to the electric network causes a significant distortion in the line current and when their overall power is no longer negligible with respect to the network power, also some distortion in the line voltage, thus deteriorating the electric supply quality. Electrical problem within malfunction protective devices, aged wiring, poor discrimination of protection system, large switching loads do contribute to the power disturbance a part from the stress placed upon the electrical system by the non-linear loads. The main objective of this project is to measure and analyse the power quality interruption that occurs in ITM especially in Block A Engineering. |
