Embodiment

[0023] Such as figure 1 As shown, a method for on-site commissioning of an intelligent substation comprises the following steps:

[0024] Step 1) debugging the substation protection unit;

[0025] The debugging of the relay protection unit is carried out by dynamically simulating the actual operation of the power system. For the debugging of protection units in digital substations, it is required to have convenient and reliable debugging tools (digital relay protection testers) for various functional requirements on site. By configuring and connecting intelligent components, output information flow, and automatically detect output information, To verify the protection function. The commissioning of the substation protection unit specifically includes the following steps:

[0026] Step 11) Select digital relay protection tester

Abstract

The invention relates to an on-site debugging method for a digital substation. The on-site debugging method includes steps of firstly, debugging protection single bodies of the substation; secondly, basically debugging primary equipment of the substation; and thirdly, debugging a system of the substation. Compared with the prior art, the on-site debugging method has the advantages of simplicity, convenience in use, high testing accuracy and the like.

Description

technical field [0001] The invention relates to the field of power system testing, in particular to an on-site debugging method for an intelligent substation. Background technique [0002] The digital substation is one of the core platforms for energy conversion and control in the construction of the strong smart grid of the State Grid Corporation of China. It can better meet the requirements of smart grid informatization, automation and interaction. [0003] The digital substation adopts a hierarchical distributed structure. The entire substation is divided into a station control layer, an interval layer and a process layer. Devices, measurement and control devices, and other smart devices, the process layer is a new concept proposed in the IEC61850 standard, which includes smart I / O units, electronic transformers, smart primary equipment, smart sensors, etc. In-situ collection and direct control of intelligent primary equipment. [0004] The basic features of a digital ...
