黑龙江电网全电磁暂态建模研究

A study on the transient modeling of all electromagnetics in Heilongjiang power grid

东北电网现已形成了具有3回常规直流、1回特高压分层直流的交直流混联大电网。交直流交互作用逐渐成为影响电网安全稳定的关键因素,电力系统仿真规模和仿真精度之间的矛盾日益显现。为准确认识电网特性,展开黑龙江电网全电磁暂态建模研究工作,依托ADPSS仿真平台,实现黑龙江省交流电网骨干网架机电模型与电磁模型的转换、交直流电网拼接。经验证,全电磁暂态模型高精度的仿真为研究大电网运行机理、掌握电网运行特性提供有力支撑。

Northeast power grid has now formed with 3 conventional DC,1 back UHV stratification DC mixed with the large grid.The interaction of AC/DC has gradually become the key factor affecting the safety and stability of power grid,and the contradiction between the scale and accuracy of power system simulation is becoming more and more obvious.In order to accurately understand the characteristics of the power grid,carry out the research work of the whole electromagnetic transient modeling of Heilongjiang power grid,rely on the ADPSS simulation platform,realize the transformation of the mechanical and electrical model of the backbone grid frame and the electromagnetic model of Heilongjiang province,the splicing of the AC/DC power grid,and the high precision simulation of the all-electromagnetic transient model provides strong support for the study of the operation mechanism of the large power grid and the operation characteristics of the power grid.
