Example Embodiment

[0078] The present invention will be further described below in conjunction with specific examples and drawings.

[0079] The purpose of the present invention is to propose a distributed power flow controller (DPFC) modeling method based on ADPSS, to study a modeling simulation method that can not only ensure the accuracy of DPFC simulation, but also take into account the simulation scale, so that the DPFC device can be safe in the actual power grid. Stable operation provides more reliable, comprehensive and refined theoretical support. The implementation steps are as follows:

[0080] 1) Such as figure 1 As shown, in the ADPSS / ETSDAC simulation environment to build a double-circuit transmission system simulation model, the voltage at the transmitting end is Vs, the voltage at the receiving end is Vr, and the Y-△ transformers at the head and end of the transmission line are respectively T 1 And T 2 , The impedance of transmission line 1 is XL 1 , The impedance of transmission line ...

Abstract

The invention provides an ADPSS-based distributed power flow controller modeling and simulation method. Electromagnetic transient simulation of a distributed power flow controller on a power system digital simulation system ADPSS platform can be realized. The method comprises the steps that a double-loop power transmission system simulation model is established under the ADPSS/ETSDAC simulation environment, a DPFC device is appropriately simplified by using the UDM function module of the ADPSS/ETSDAC, a series side current converter equivalent mathematical model is established by using an equivalent voltage source, and a parallel side current converter equivalent mathematical model is established by using an MMC mean value model. The dynamic and static characteristics of the DPFC device and the regulation and control function for the system power flow can be reflected under the premise of guaranteeing the simulation scale so that the simulation accuracy can be guaranteed and the simulation time can be shortened; and the more reliable, more comprehensive and more detailed theoretical support can be provided for actual power grid safe and stable operation of the DPFC device, and the foundation can be laid for popularization and application of the distributed power flow controller.

Description

technical field [0001] The invention relates to the field of modeling and simulation of flexible power transmission in power systems, in particular to an ADPSS-based distributed power flow controller modeling and simulation method. Background technique [0002] Flexible AC Transmission System (FACTS), as the future development direction of power transmission technology in the 21st century, has received great development and worldwide attention since it appeared in the 1990s. FACTS technology is a major reform of traditional AC power system by using modern high-power power electronic technology. It uses modern high-power power electronic technology to quickly adjust the phase angle, reactive power, reactance and other parameters in the AC system to improve the stability and reliability of the AC system and make the traditional AC transmission system more flexible and flexible. Make full use of the original resources of the transmission system to meet the goal of safe, reliab...
