Description

technical field

[0001] The invention belongs to the technical field of measurement and identification of load models of modern power systems, and in particular provides a load modeling system based on actual measurement, which is suitable for application in production practice. Background technique

[0002] At present, power system digital simulation has become the main tool for power system design, planning and operation, and the corresponding decision-making is all based on the results of digital simulation. The accuracy of the simulation results has an important impact on the safe, reliable and economical operation of the power system. The mathematical model of each component of the power system and the mathematical model of the whole system constituted by it are the basis of digital simulation, and its accuracy directly affects the simulation results and the decision-making scheme based on the simulation results. For a long time, people have conducted in-depth research ...

Embodiment Construction

[0019] 1 On-site measured data

[0020] (1) According to the actual situation of the system, and the substation where the system scheduling staff needs to install the microcomputer load dynamic characteristic recorder, based on three aspects of data: ① actual load survey statistics (or estimated data by professional load engineers); ②Sensitivity analysis of the load at this point in the power system simulation calculation; ③Whether it belongs to a typical load (load model vector base).

[0021] (2) Install a microcomputer-based load dynamic characteristic recorder. After selecting a substation, you can install a microcomputer-based load dynamic characteristic recorder together with the staff of the relay protection team. Sufficient PTs, CTs and a telephone communication are required line.

[0022] (3) Terminal correspondence setting, the rear terminals of the recorder can be defined in the background setting software. Since each converter plug-in is composed of four current c...
