1996年夏天,美国WSCC电网两次大范围停电,引起世人震惊。2003年,美国又发生举世瞩目的“8·14”大停电事故。美国、加拿大等国的专家们事后期望对当时的过程通过仿真来重现,以期找出事故的原因与责任,但事故重现异常困难。专家们逐渐认识到:一个多年来人们一直都尽力在回避的问 In the summer of 1996, two large-scale power outages occurred on the WSCC power grid in the United States, causing the world’s shock. In 2003, another “8 · 14” blackout occurred in the United States. Experts from the United States, Canada and other countries later expected to reappear the process at that time through simulation to find out the cause and responsibility of the accident, but the recurrence of the accident was extremely difficult. Experts have come to realize that for a long time people have been trying their best to avoid asking
