对于美国西部电力系统1996年7月2日大停电事故的初步认识

美国西部电力系统（ＷＳＣＣ）在安全运行多年后，近期连续发生大面积停电事故（１９９４年１２月１４日，１９９６年７月２日，１９９６年８月１０日等）［１］，其中以１９９６年７月２日发生的事故涉及面为最广，停电后果最严重，遂引起广泛注意。本文根据一些初步资料，介绍这次事故的概况、初步分析和对其的认识，以供进一步了解和讨论。     

全国开展安全生产大检查 电力等成重点行业

2013-06-09,国务院办公厅发出《关于集中开展安全生产大检查的通知》。《通知》指出,近期接连发生多起重特大事故,暴露出一些地方和企业安全意识淡薄,隐患排查治理不认真,安全责任不落实,安全监管不到位,打击非法违法和治理违规违章行为不得力等问题。为深刻吸取事故教训,切实加强安全生产工作,经国务院同意,定于2013年6月至9月底,在全国集中开展安全生产大检查。检查范围包括全国所有地区、所有行业领域,所有生产经营企事业单位和人员密集场所。重

2004年全国电力安全生产情况通报(摘要)

1　　2004年全国电力安全生产基本情况　　　　2004年,电力行业安全生产形势总体平稳。全年电力生产没有发生重特大人身伤亡事故,没有发生重特大电网事故,没有发生特大设备事故。全年共发生电力生产人身死亡事故11起,死亡11人,同比减少了9人;发生电网事故196次,同比增加14次;发生设备事故551次,同比减少106次,其中重大设备事故1次。2004年电力施工、设计企业发生4起重大人身伤亡事故,死亡20人,伤9人。　　　　以上16起事故都给人员生命和国家财产造成了重大的损失,除一起事故正在调查中外,其他15起事故的原因都已认定,其中违章作业导致的事…     

安全生产当应如履薄冰

素以安全、快捷、舒适而备受公众青睐的动车,在7.23追尾事故中,造成了35人死亡、192人受伤的惨剧。血淋淋的事实再次警示我们:生命高于一切,安全重于泰山。7月份以来,国内接连发生多起重特大事故。特别是7月22日,京珠高速信阳市境内一辆超载大客车发生燃烧,造成41人遇难。23日,国务院安委会发出通知,要求各地各部门有效防范和坚决遏制重特大事故发生,确保人民群众生命财产安全。就在通知发出后的当晚,甬温线发生7.23特大铁路交通事故。

Users' Needs Lighting, Start-Up Power, Transportation, Mechanical Utilities, Heating, Refrigeration, and Production

The needs for emergency and standby power to enhance industrial and commercial power systems are frequently left wanting due to ignorance of the needs or of the systems available to satisfy the needs. This paper discusses various situations which require or desire emergency or standby power and mentions suitable systems for each application. The areas discussed include lighting, start-up power, transportation, mechanical utilities, heating, refrigeration, and production.     

Grades, Quizzes, Motivation, and Computers

The following paper describes the use of a simple FORTRAN computer program that may be used to determine course grades. The program is based on processing a set of IBM punched data cards. Each card contains the name of a student and all of his grades, including the final examination grade. The program may also be used to predict the final examination grade, based on previous quiz grades, and then, in turn, to predict the final course grade. It is thus possible to use this program periodically throughout the entire semester in order to provide the student, as well as the instructor, with a measure of his progress.

Dual-rotor, radial-flux, toroidally wound, permanent-magnet machines

A novel machine family-dual-rotor, radial-flux, toroidally wound, permanent-magnet (RFTPM) machines-is proposed in order to substantially improve machine torque density and efficiency. After the principles of operation, configurations, and features are discussed, the machine design and optimization guidelines are given. A prototype has been designed, built, and tested. The measured torque density of the prototype, which well matches the design value, is almost three times of that of the induction machine with the same power of 3 hp and speed. Meanwhile the efficiency is still kept high and the material cost is kept low by using ferrite magnets. Three novel approaches are proposed to reduce the cogging torque in the RFTPM machines, whose validity is verified by finite-element analysis results and experimental measurements.     

A new soft-switched, thyristor-based, regenerative, quasi-resonant,current regulated inverter

A variety of soft-switching techniques have been proposed to reduce the switching losses and EMI problems that occur with higher switching frequencies in hard-switched converters. In this paper, a new, quasi-resonant, soft-switched, three-phase inverter is presented which uses 12 thyristors as the power electronic switches, and hence has potential for use in high-power applications. The converter is fully current-regulated, suitable for high-performance motor drive applications, and is capable of 4-quadrant operation to allow regeneration back into the DC supply. The operation and the control of the inverter are described in detail and simulation and experimental results are presented     

Industrial system grounding for power, static, lightning, andinstrumentation, practical applications

Practically every structural steel building erected for industrial use incorporates reinforcing steel bars installed in the concrete footings. This, without any additional effort, constitutes a grounding electrode. The quantity of electrodes is directly related to the building area. When the structural steel framework is erected and interconnected, these electrodes are also interconnected in a parallel arrangement. Similarly, high-voltage metal transmission towers are installed using a metal footing base embedded in a concrete filled hole. The four tower legs are effectively in parallel and offer an adequate low ground resistance such that additional electrodes are generally not required. This brings us to the main point: the reinforced concrete footings, reinforced concrete grade beams, and other reinforced concrete structures provide, with a little work, an effective, reliable, and cost attractive system grounding vehicle
