我省当前电力供需形势的几点思考

长期缺电曾经一直困扰着工农业生产和人民生活,电力工业一直成为制约我国经济发展的"瓶颈"行业。改革开放以来,实行多家办电、多渠道集资办电一系列政策,取得了"七五"到"八五"10年平均每年发电量增长速度全国为9．45％、江西为7．99％的持续快速增长,为社会经济发展提供了有效的电力支撑。随着我国经济体制改革的深化,全国经济发展成功地实现了"软着陆",两个根本性转变初见成效。开始结束了计划经济时代的"短缺经济",呈现了总量相对充裕、结构需要调整的态势。作为国民经济基础产业的电力工业也不例外,同样一改长期缺电局面。一向"…

Future economy of electric power generated by nuclear and coal-fired power plants

The available literature (1969–1978) on estimated and predicted costs of nuclear and coal-fired power plants has been examined. The complexity and difficulty of predicting the nuclear power economy are discussed. Scenarios are developed for various capacity factors and fixed charge rates to predict the national electric power economy generated by nuclear and coal-fired power plants between 1979 and 1993.

The hydrogen economy is complementary and synergetic to the electric economy

There is growing support to electrifying our economy by getting off of fossil fuels by producing renewable energy by wind and solar photovoltaic plants and using batteries to balance production and demand or to store energy onboard vehicles that cannot move along electric lines. Unfortunately, this proposal is pushed forward negating the value of hydrogen as an energy store. As here commented, the hydrogen economy is not competitive, but complementary and synergetic to the electric economy, and both should be promoted together to secure a faster transition towards a CO₂ emission-free economy.     

To regulate or not to regulate off-grid electricity access in developing countries

As off-grid electrification receives global attention in the Sustainable Energy for All initiative, the role of regulation for this alternative form of electricity delivery requires a careful investigation. This paper asks whether the activity has to be regulated or not. It then tries to find out where regulation can be used and what type of regulation is appropriate. It suggests that for product-type delivery options, there is no justification for regulatory intervention in the sense of utility regulation but such intervention makes sense in the case of mini-grid-based off-grid delivery options. The paper considers the pros and cons of a generic license waiver, a simplified regulatory arrangement and a full-fledged regulatory supervision and suggests that a light-handed approach is appropriate in general to promote the activities of the sub-sector but more formal approaches may be required if the players do not abide by the rules. The paper also highlights some regulatory challenges and issues.     

利用地热资源发展西部经济

地球是一个大热库,蕴藏着巨大的热能,这种热能通过火山爆发、温泉、喷泉、岩石的热传导等形式被源源不断地带出地表,这就是地热能。地热能既为水、也为热、又为矿,是一种有用的资源,具有分布广、洁净、可直接利用等优点。　　地热能的开发利用包括发电和非发电利用两方面。世界各国利用地热能的经验表明：高温地热资源 (大于 150℃ )主要用于地热发电;中温 (90℃至 150℃ )和低温 (小于 90℃ )地热资源则以直接利用为主,大多用于采暖、干燥、工业、种植、养殖、医疗、旅游及日常生活用水等方面。　　地热能的开发具有悠久的历史。…     

Applications of superconductivity to electric power systems

The interest in superconducting systems stems from their promise to be more efficient, smaller, and lighter than those made from conventional conductors. The types of applications in which superconductivity has the potential to be effective in an electric power system can be separated into two general classes. The first type includes those technologies in which superconductivity is simply a replacement of existing resistive materials, for example, cables, motors, generators, and transformers. The second type includes technologies that will be enabled by superconductivity and that have little or, at most, limited capability if conventional resistive or other materials are used. Examples are superconducting magnetic energy storage (SMES) and large fault current limiters (FCL). Before looking at the applications under development the article discusses the discovery and development of superconductivity     

A scenario for geothermal electric power development in Imperial Valley

The growth of geothermal electric power operations in Imperial Valley, California is projected over the next 40 yr. With commercial power forecast to become available in the 1980s, the scenario considers three subsequent growth rates of 40, 100 and 250 megawatts (MW) per year. These growth rates, along with estimates of the total resource size, result in a maximum level of electric power production ranging from 1000 to 8000 MW to be attained in the 2010 to 2020 time period. Power plant siting constraints are developed and used to make siting patterns for the 400 through the 8000 MW level of power production. Two geothermal technologies are included in the scenario: flashed steam systems which can produce their own cooling water from the geothermal steam condensate and which emit noncondensable gases to the atmosphere; and high pressure, confined flow systems which inject all the geothermal fluid back into the ground. An analysis of the scenario is made with regard to well drilling and power-plant construction rates, land use, cooling water requirements, and hydrogen sulfide emissions.
