"十三五"期间,河南电网外部直流受电规模和内部风、光等不可控可再生能源都将大幅增长,从而给河南电网的调峰带来挑战。为有效分析该环境下的调峰形势,在充分计及河南电网内部分区断面约束、复杂电源结构和调度原则的基础上,设计了河南电网调峰形势评估计算模型,对河南电网2020年的调峰形势进行了计算分析。分析时,为使得结果符合未来实际,结合河南经济增长新趋势以及国家电源建设新政策,分析了原始规划场景、负荷低增长场景以及纯凝火电冻结建设3个场景。结果表明:河南电网调峰容量不足问题主要出现在冬季,若负荷按规划预测增长,通过纯凝煤电深度调峰或少量弃风调峰可以满足调峰平衡需求;而若负荷低增长,则无论电源按规划建设,还是冻结纯凝煤电建设,通过纯凝煤电深度调峰或弃风调峰均无法满足调峰平衡需求,需要采用其他调峰手段。 相似文献

Like the master puppet makers of the classic folk tales, artificial intelligence (AI) engineers have built some marvelous machines. The first 50 years of AI focused on programming computers to perform tasks that previously only humans could do tasks such as speech, driving, planning, problem solving and vacuuming. The principal challenges have been to create suitable language systems and inference engines and then to more or less manually stuff those with sufficient facts, heuristics and algorithms to perform well-defined tasks. To get there, we need a singularity of artificial neo-creationism, where we launch artificial beings into the world that can adapt, learn and evolve themselves. The term neo-creationism means an intentional effort to populate the world with intelligent entities initially engineered by humans. The biblical story of Genesis, the heart of creationism, provides an apt foil for understanding the goals and scope of the R&D program advocated here. To reach the goal reasonably quickly, we should equip these creatures with as much capability and knowledge as possible. 相似文献

Most electrical engineering programs have a capstone design course, but lack a suitable design experience in the junior year. This makes the capstone course very difficult for students and compromises its pedagogical aims. A good design experience offers opportunities for learning to identify key operational concepts, to identify and remedy procedural and factual knowledge deficits, and to exercise judgment. The design problem should be open-ended, moderately difficult, and common to all groups. We use a design contest as a vehicle for teaching design in the junior-year analog electronics course, in lieu of conventional laboratories. Students design and build analog circuitry to autonomously control a small robotic vehicle. The contest culminates in a competitive tournament. Students' questionnaire responses indicate that the contest is a useful learning tool, increasing interest in electrical engineering and well worth the time spent. They indicate that contests are preferable to conventional labs for learning and understanding course material, for motivating them, and for providing an engineering experience 相似文献

呼兴电网联网后存在诸多的暂态安全稳定问题,其中乌兰浩特地区机组暂态功角稳定问题尤其突出,威胁着电网的安全稳定运行。通过对乌兰浩特地区机组暂稳问题模拟计算的分析,采取在音扎线装设失步振荡解列装置,可使系统发生故障后将失步机组从系统中解列,保证主网和解列地区电网暂态稳定。 相似文献
