Intelligent distributed feeder automation logic test system

Abstract

The invention relates to an intelligent distributed feeder automation logic test system. According to the intelligent distributed feeder automation logic test system, the normal working or the fault state of a tested loop is simulated, a voltage signal and/or a current signal is generated by a fault simulator, a corresponding switching value signal is generated by a switch simulator and sent to a power distribution terminal in the tested loop through a communication interface as a test signal, the power distribution terminal feeds the switching state information formed according to the test signal back to the test system through the communication interface, and an ordered, accurate and efficient intelligent distributed feeder automation logic test for the power distribution terminal is realized by judging whether the switching state information meets processing logic during the normal working or the fault state of the tested loop.

Description

technical field [0001] The invention relates to the field of power distribution automation, in particular to an intelligent distributed feeder automation logic test system. Background technique [0002] Distribution automation is the use of modern electronics, computers, communications and network technologies to integrate the online and offline data, distribution network data and user data, power grid structure and geographic graphics of the distribution network to form a complete automation system. The modernization of monitoring, protection, control, power consumption and distribution management of power grid and its equipment in normal operation and accident state. Distribution network automation is a stage in the development process of power system automation. The distribution network that implements distribution network automation generally refers to the medium and low voltage distribution network of 10kV and below that directly faces end users.

Problems solved by technology

[0004] However, since the feeder automation (FA) equipment has undergone type tests and logic tests before being put into operation, the laboratory test uses the switch-network cable direct connection method for communication, which is not completely consistent with the actual communication conditions on site; in addition, the temperature of the laboratory test The wet environment is also inconsistent with the field; after the equipment is put into operation, the grid and configuration changes and the test needs to be re-tested in the laboratory; therefore, logic tests need to be carried out on-site. In the initial stage, manual on-site testing is adopted, using walkie-talkies There is a large error in the timing, and the manual test consumes a lot of manpower and takes too long, and there are few types of faults that can be tested

[0005] In addition, during the installation, commissioning and operation of automation equipment, it was found that due to the large variety of equipment and complex on-site conditions, there were problems such as unclear processes in on-site construction and commissioning, and there were many manufacturers with different software, lacking a standardized commissioning process
