Abstract

On October 17, 2013, the Federal Energy Regulatory Commission (FERC) approved the North American Electric Reliability Corporation (NERC) Reliability Standard for transmission planning, TPL-001-4. With respect to transient stability assessment, TPL-001-4 requires more extensive annual assessments, establishment of criteria for transient stability, simulation of actual actions of protective relays and Special Protection Systems (SPS), inclusion of protection system failure and relay failure contingencies, and criteria or methodology for identification of system instability such as cascading, voltage instability, or uncontrolled islanding. To comply with this new Reliability Standard, several aspects of transient stability study need to be enhanced: (1) selection of study cases, and of contingencies potentially causing reliability violations or producing more severe system impacts including cascading; (2) inclusion of actual actions of protection systems and SPS; (3) automation of procedure to identify transient stability violations based on the established criteria; and (4) mechanism for identifying and simulating cascading.

增强NERC可靠性标准TPL-001-4合规的稳定性仿真

2013年10月17日，美国联邦能源监管委员会(FERC)批准了北美电力可靠性公司(NERC)输电规划可靠性标准TPL-001-4。关于暂态稳定性评估，TPL-001-4要求更广泛的年度评估，建立暂态稳定性标准，模拟保护继电器和特殊保护系统(SPS)的实际动作，包括保护系统故障和继电器故障事故，以及识别系统不稳定性的标准或方法，如级联，电压不稳定或不受控制的孤岛。为了符合这个新的可靠性标准，暂态稳定研究的几个方面需要加强:(1)研究案例的选择，以及可能导致可靠性违规或产生更严重系统影响(包括级联)的突发事件的选择;(2)纳入保护系统和SPS的实际行动;(3)基于既定标准识别暂态稳定违规行为的程序自动化;(4)级联识别与模拟机制。
