On-line monitoring data collection system of power system

Abstract

The invention relates to an on-line monitoring data collection system of a power system. The on-line monitoring data collection system comprises a device information collection instrument. A main control chip is arranged on the device information collection instrument and is connected with an ethernet network interface and a transparent forwarding module. A GPRS module, a transformer chromatographic analyzer, an intelligent direct-current screen, and a voltmeter are connected to the transparent forwarding module. A station machine, an electricity quantity inquiring display screen, and a firewall are connected to the ethernet network interface; and the firewall is arranged between the upper-level network and the ethernet network interface. The device information collection instrument employs a 32-bit embedded system as a main data processor and a network chip manufactured by the Intel company is used for processing 100-M ethernet information. With the system, data of the transformer station can be collected effectively and on-line detection is also realized; and thus the transformer station data can be collected and utilized effectively and the data can be analyzed and collected conveniently. And a query interface is also arranged for query, so that convenient management and usage can be realized.

Description

technical field [0001] The invention relates to an online monitoring data acquisition system of a power system, belonging to the technical field of data acquisition. Background technique [0002] In order to ensure the safe and efficient operation of power production, higher requirements are put forward for the condition-based maintenance of power equipment. Since the condition-based maintenance mainly depends on the status detection and online monitoring of the equipment in operation, the operation status detection and online monitoring of power equipment always play an important role in the safe production of electric power. [0003] However, the existing substation equipment information transmission mode basically stays in the point-to-point mode, which is limited by the communication protocol and other related conditions, resulting in a relatively reduced amount of transmitted information and a slow transmission speed.

[0003] However, the existing substation equipment information transmission mode basically stays in the point-to-point mode, which is limited by the communication protocol and other related conditions, resulting in a relatively reduced amount of transmitted information and a slow transmission speed. Many devices with serial communication functions fail to access, so that device information is not fully utilized

Since various equipment systems require different dedicated channels, the channels are wasted, and the communication reliability is relatively poor, which affects the real-time and effectiveness of equipment information
