A computer package-NETOMAC developed by Siemens power transmission and distribution group is used to analyze system voltage collapses in time-domain. The components, which significantly affect the voltage stability, are modeled in detail with the NETOMAC controllers in the simulation process. The advantage of NETOMAC is that it can simulate nearly all dynamic elements such as various loads, controllers, governors and regulators in the system and nearly there is no bus number limit.

A computer package-NETOMAC developed by Siemens power transmission and distribution group is used to analyze system voltage collapses in time-domain. The components, which significantly affect the voltage stability, are modeled in detail with the NETOMAC controllers in the simulation process. The advantage of NETOMAC is that it can simulate nearly all dynamic elements such as various loads, controllers, governors and regulators in the system and nearly there is no bus number limit. Furthermore, it can show the power angle and voltage profiles at the same time by which the factor of voltage collapse whether caused by angle or voltage instability is observable. For illustrative purpose a test system from CIGRE is applied to NETOMAC and the results are promising.

提出了用西门子输配电集团开发的一个计算机软件包———NETOMAC对电力系统电压崩溃事故进行时域分析.在仿真过程中,严重影响电压稳定性的组成部分被NETOMAC控制器详细地加以描述.NETOMAC的优点是利用模块导向语言,其控制器能模拟差不多全部的动态元件且系统的节点不受限制.而且,它能同时显示功角和电压特性以判断系统电压崩溃事故的起因.为了比较目的,将CIGRE的一个测试系统用于NETOMAC,所得结果令人满意.

The defects of the assessment methods for traditional power system voltage collapse are analyzed. The necessity of conducting risk assessment of voltage collapse in electricity market environment is expounded, and an approach to assess the risk of power system voltage collapse is proposed, in which the probability and consequence of voltage collapse are comprehensively considered and the risk index is quantified,and the foundation to determine optimal operation mode is provided by giving consideration to both risk index and economic benefit. The assessment results for 6-bus system and IEEE 30-bus system show that the proposed approach is feasible and effective, and the risk assessment software of voltage collapse programmed by this approach is practicable.
