Substation intelligent operation system and its control method

Abstract

The invention relates to an intelligent running system for a distribution substation and a control method thereof. The intelligent running system for the distribution substation comprises a plurality of switch cabinets which are connected to a power-supply incoming line and are provided with multipath outgoing lines, wherein outgoing line switches and electric quantity data acquisition devices are arranged on all the outgoing lines; the electric quantity data acquisition devices are all connected to a data concentrator; the data concentrator is connected to a PLC (Programmable Logic Controller); the PLC is connected to the outgoing line switches on the switch cabinets; and the data concentrator is connected to a primary station master control terminal, which is located at a far end and isprovided with a short message sending module or a phone number dialing module, through a wireless or wired network. The control method of the intelligent running system comprises the following steps:the data concentrator concentrates the data sent by the electric quantity data acquisition devices and calculates the whole real-time electricity-using load; the primary station master control terminal sets load control indexes of the distribution substation and sends the load control indexes to the PLC; and the PLC controls the switch-on/off of the outgoing line switches. The intelligent runningsystem for the distribution substation provided by the invention has the advantages that the safety reliability is high, the degree of intelligence is high, and the unmanned operation demand of the distribution substation is met.

Description

technical field [0001] The invention relates to a monitoring system for a transformer substation, in particular to an intelligent operation system for a transformer substation and a control method thereof. Background technique [0002] With the continuous development of science and technology, computers have penetrated into every corner of the world, and power systems have inevitably entered the era of microcomputer control. With the development of power grid construction, the future control of power grid operation will be more stringent, the technical difficulty of substation operation will continue to increase, and the professional requirements for on-duty personnel will also continue to increase. Deal with it accordingly. With the promotion of digital substations, there are more and more signals in substations. If it is judged manually, one is that there is a lag phenomenon, which cannot be discovered and processed in time, and the other is that human factors may cause e...
