摘　　要：随着电力系统近些年的发展,电力系统广泛采用了广域量测系统,数据的获取因而已经非常方便和及时。基于现有技术条件提出了利用广域量测系统采集所需的数据进行负荷建模。考虑到电力系统存在持续的"类噪声"信号,介绍了小扰动条件下,基于该类信号,通过线性化处理,推导出的一种综合负荷辨识模型,并在此基础上简要介绍了针对该模型的负荷参数辨识方法,在CEPRI-36节点系统中仿真结果证实了所提出模型的可行性。With the development of power system in recent years, wide-area measurement system has been widely a- dapted. The acquisition of data has been very convenient and timely. Considering a kind of ambient signal, which is prevalent in the power system, an identified composite load model is proposed under the condition of small signal, by a method of linearization. Then, the identification method is briefly introduced. Simulation is carried out in CERPI 36-node system, and result confirms the feasibility of the proposed method.
