An RTU is a control device that helps the master device (SCADA) to monitor and communicate with devices in the grid placed in different geographical locations. RTUs are used in a broad range of electrical and process automation devices wherein supervisory control and data acquisition (SCADA) is required to monitor and control the equipment. RTUs collect data from field equipment and communicate commands from the master device. This is done through a wired connection (telephone line, cables, or Ethernet) or wireless connection. The operators receive data in real time so that they are aware of the complete grid situation and can make any changes to the grid when required. RTUs increase automation in substations, leading to optimal distribution of power. They also correct any anomalies that may lead to loss of power in transmission and distribution (T&D), reduce equipment damage, and improve power quality and reliability. RTUs can be used to control and monitor water treatment and distribution plants, power T&D operations, and oil and gas lines.

Substation automation is the upgrading of existing electric power substations. It involves integrating intelligent technologies and equipment such as relational databases and advanced communication systems into power grids. Automating substations allows electric utilities to monitor and control their T&D processes remotely， thus ensuring proper power distribution.

Generators are devices that convert mechanical energy into electric energy. Sources of mechanical energy include internal combustion engines, hand cranks, compressed air, and reciprocating steam engines.

核仪表系统(RPN)是核电厂仪控系统的重要组成部分。介绍福清核电厂一期数字化核仪表系统的结构、功能、设计要求和设计特点,并从设计的角度就RPN与安全级数字化仪控系统的功能划分与岭澳核电站二期进行比较。结果表明,福清核电厂一期数字化RPN设计能较好地满足系统的功能要求,为后续项目RPN优化设计提供了借鉴。

在分析现有基于集对分析的年径流丰枯分类方法不足的基础上,考虑径流等级划分的模糊性和径流的年内分布特性,提出模糊化径流分级标准,并引入基于径流分布的年内丰枯贡献权重因子,得到年径流对于各个等级的综合隶属度,进而利用集对分析方法判断年径流的丰枯等级。利用所提方法对溪洛渡径流丰枯等级进行分析,结果表明该方法较于单一的集对分析方法能更好的描述径流丰枯状态。

为了研究气候变化对径流的影响,选择黄河上游河源区为典型流域,构建多变量Copula联合分布模型,分析流域内主要气象要素与径流的相互响应关系。通过对多元相依结构分析,得到主要气候变化要素与径流变化的定量关系。结果表明,黄河上游吉迈水文站以上流域,径流受气候变化影响明显。长期以来主要气象要素,气温、降水、潜在蒸发能力(Penman-Monteith公式计算)与径流量的相依度指数分别为0.03、0.46、0.13,且在不同时期影响径流变化的主导因素各异。黄河上游径流受降水、冰雪、冻土融水和地下水共同补给,径流自演化过程复杂。 

This guide helps users get started with the U.S. Department of Energy/National Renewable Energy Laboratory Fuel Cell Power (FCPower) Model Version 2, which is a Microsoft Excel workbook that analyzes the technical and economic aspects of high-temperature fuel cell-based distributed energy systems with the aim of providing consistent, transparent, comparable results. This type of energy system would provide onsite-generated heat and electricity to large end users such as hospitals and office complexes. The hydrogen produced could be used for fueling vehicles or stored for later conversion to electricity.

Fuel cells are a promising technology as an alternative for portable power applications, because they offer higher power densities, do not include moving parts, and thus are free of noise and vibrations. At the current state of development, fuel cell systems cannot effectively use hydrocarbon fuels unless they have been processed, or reformed, into a syngas consisting of hydrogen, carbon monoxide, and other species. Conventional reforming technologies utilize catalysts which may have strict requirements on fuel purity and operating conditions. The development of a robust non-catalytic technique has the advantage of using a variety of logistics fuels. In this project, conversion of various fuels was demonstrated in two different non-catalytic reactors. The conversion of butanol and Jet-A were demonstrated in a filtration reactor consisting of a packed bed of spheres. A second reactor, consisting of counterflowing channels, has the advantage of stationary reactions zones and the ability to operate continuously. Conversion of heptane was demonstrated in this reactor and a computational study was conducted to understand the scaling of the reactor for various applications. These results show the promise of non-catalytic technologies for the reforming of a wide range of fuels.
