摘要
针对暂态稳定分析中发电机和相关控制系统的具体特点,将传输模块划分为大量的线性和少量的非线性表达。利用小干扰稳定分析中的插入式建模技术处理线性部分,先将发电机及辅助控制设备转化为两类基本的传输块,形成相应的数学表达,结合网络方程构成全系统计算模型。与常规的方法相比,在发电机建模、模型修改和状态变量的初值计算方面更为方便。该方法的有效性在一22节点6机系统上进行了验证。
In view of the particular characteristics of generator and related control system models in the transient stability analysis, transfer modules are divided into a large number of linear equations and a small amount of non-linear equations. Linear modules are treated by the plug-in modeling technique which is used in the small signal stability analysis. With generators and related control equipment presented by two types of basic transfer blocks, corresponding mathematical models are established. With network equation considered, the computation model of entire system is then formed. Compared with the conventional modeling approaches, the proposed method is convenient in generator modeling, module modification and the computation of state variable initial values. The proposed technique is validated on a 22-bus 6-generator test system.
