| Zusammenfassung: | A protection system for an electrical system is used for avoiding voltage falling caused by reactive power characteristic of the electrical system. A main equipment for acquiring system electric quantity of one or more upper transformer stations is utilized to detect the voltage falling generated by reactive power characteristic of the electrical system, and send the detect signal of voltage falling to terminal equipment used for acquiring system electric quantity of one or more lower transformer stations. Each terminal equipment drops off load in sequence from the load which is most influenced by voltage falling caused by reactive power characteristic based on the load voltage and the load current of a load bus. |
