Free download-Freecal for Test and Measurement
Someone would like to construct a comprehensive and flexible softsolution that drives test and control interests, here a 100 percent free software(soucecode) named FreeCal from Codeproject
might be a good news for developers.
Codeproject is also a website that supplies free materizal with comprehensive branches.
Now below is a brief information taken from Codeproject.
FreeCal - GPIB Instrument Automation for Metrology Test and Measurement
By Scott Page
FreeCal is a free 100% .NET suite of utilities and instrument drivers for controlling multiple instruments in a Test and Measurement environment.
Features
Base instrument libraries for Signal Generators, Spectrum Analyzers, Network Analyzers, Power Meters, Function Generators, Universal and RF/Microwave Counters, Attenuator/Switch Drivers, EEPROM Power Sensors, Digital Multimeters and any other type of instrument that can be controlled remotely. All categories have specific instruments that have been coded for compatibility (due to the fact that all instruments have their own specific language for communication).
Charts/graphs are integrated into the code with the use of ZedGraph: A flexible charting library for .NET (Thanks to JChampion for ZedGraph, many sleepless nights have been avoided developing an integrated charting library).
Procedures for Power Sensors, Signal Generators, Spectrum Analyzers and Network Analyzer Calibration Kits have already been developed (so far most of them partially completed due to time), but they are not difficult to create as you will see in the examples below.
Several conversion functions included to aid in the development and presentation of data: Frequency conversion from one range to another (i.e. MHz to GHz), Amplitude and Time conversions are also included as a base for almost all formulas and instrument communication.
I recently started construction of a visual editor that allows "drag and drop" style test creation. It is included in the source and can be found in the demo under the Tools menu.
Integrates with MySQL using the MySQL.NET Connector. I have created a number of data classes that ease the task of saving result data to a MySQL database.
Various forms have been created for several of the instrument categories, like Network Analyzers. One of the most difficult tasks in RF/Microwave is downloading and manipulating data from the Agilent 8500 Series NWA, so I spent a lot of time writing the NWA data transfer classes.
Because every instrument has its own tolerances and capabilities, the drivers have been written to include all of this (any missing information is easily added as it is all structure based).
Instrument drivers and procedures are written with a "One Procedure Any Instrument" mindset. You can write one procedure that can calibrate any instrument of the same category. This is due to each instrument driver including the specifications for each test.

Online CT Diagonistics Without Contact of Primary
Online CT Diagnostics Without Contact of Primary
by swipower @ 2009-08-01 – 08:08:53
Keywords: CT, Online Diagnostics,Error, failure
The below summary and attached product information focus on two major issues:
1. Insulation
2. Metering
The first is realized through an online equivalent loop admittance diagnostic methods, which can be a complement to other methods like Dielectric loss,PD and oil analysis, actually the admittance response features with frequency vary design, which zooms out the defects parameter.
The latter, metering error, most important for income of power utilities, will be a trends for a non-offline test.
Based on experience.....
The research started from year 2006 and initiated project in year 2007. a sample product being finished in the end of year 2008.
Application Background:
Current Transformer, Voltage Transformer, Secondary wirings and Electronic energy meters are components of metering loop, among which high-voltage electronic energy meter is online calibrated periodically 6 to 12 months, and even shorter in some substations. But Current Transformer (CT) keeps running for several years until a power off accuracy calibration, metering loss will be difficult to compensate if error runs out of limits. Traditional methods employ offline comparison techniques to verify the accuracy and healthy condition of current transformer, which requires large amount of efforts on both labor and time. Power utilities also try their best to get family data that relates to accuracy or potential fault in order to avoid or decrease sudden power losses. Most common adopted techniques are active ratio, phase error test, burden measurement and harmonics. But burden measurement can only determine if secondary load is within allowed limit, which is just one of several factors that affect metering error. Ratio and phase error measurement require operator to contact primary high-voltage line for an online verification, which adds extra danger and in most cases infeasible. Harmonics gives results which are not easy for decision making of whether CT is running healthily. TM01 is an innovative CT analyzer that focuses on active composite error for metering verification and potential faults that cannot be detected through traditional ways. It also features on low-voltage injection methods that avoid high-voltage contact. Test methods are well in accordance with IEEE CT application Guide and IEC standards.

CBM-Condition Based maintenance
There is widespread discussion about CBM concept, someone refer to CBM as part of corrective and preventive maintenance, but in Wiki, the idea is:
Condition-based maintenance (CBM) was introduced to try to maintain the correct equipment at the right time. CBM is based on using real-time data to prioritize and optimize maintenance resources. Observing the state of the system is known as condition monitoring.
CBM is now applicated as solution in industrial areas, such as:
1. Electric power System
2. Aircraft
3. Large manufacturing plant
Due to quite different historic condition data and different running model, there can be difficult to fix a clear structure of how to establish a softsolution. But CBM is under fast developing and obtaining increasing application in multiple areas, a standard might be coming out in the future to guide the applications.

变压器局放检测方法简评
变压器局放检测
电力变压器局部放电检测方法有脉冲电流法、DGA法、超声波法、RIV法、光测法、射频检测法和化学方法等。
脉冲电流法
它是通过检测阻抗接入到测量回路中来检测。检测变压器套管末屏接地线、外壳接地线、中性点接地线、铁芯接地线以及绕组中由于局放引起的脉冲电流，获得视在放电量。脉冲电流法是研究最早、应用最广泛的一种检测方法，IEC-60270为IEC于2000年正式公布的局放测量标准。脉冲电流法通常被用于变压器出厂时的型式试验以及其他离线测试中，其离线测量灵敏度高。脉冲电流法的问题在于以下几方面：其抗干扰能力差，无法有效应用于现场的在线监测；对于变压器类具有绕组结构的设备在标定时产生很大的误差；由于检测阻抗和放大器对测量的灵敏度、准确度、分辨率以及动态范围等都有影响，因此当试样的电容量较大时，受耦合阻抗的限制，测试仪器的测量灵敏度受到一定限制；测量频率低、频带窄，包含的信息量少。
DGA法。
DGA法是通过检测变压器油分解产生的各种气体的组成和浓度来确定故障（局放、过热等）状态。该方法目前已广泛应用于变压器的在线故障诊断中，并且建立起模式识别系统可实现故障的自动识别，是当前在变压器局放检测领域非常有效的方法。但是DGA法具有两个缺点：油气分析是一个长期的监测过程，因而无法发现突发性故障；该方法无法进行故障定位。
超声波法
超声波法是通过检测变压器局放产生的超声波信号来测量局放的大小和位置。超声传感器的频带约为70～150千赫兹（或300千赫兹），以避开铁芯的铁磁噪声和变压器的机械振动噪声。由于超声波法受电气干扰小以及可以在线测量和定位，因而人们对超声波法的研究较深入。但目前该方法存在着很大的问题：目前的超声传感器灵敏度很低，无法在现场有效地测到信号；传感器的抗电磁干扰能力较差。因此，超声检测主要用于定性地判断局放信号的有无，以及结合脉冲电流法或直接利用超声信号对局放源进行物理定位。在电力变压器的离线和在线检测中，它是主要的辅助测量手段。
RIV法
局部放电会产生无线电干扰的现象很早就被人们所认识。例如人们常采用无线电电压干扰仪来检测由于局放对无线电通讯和无线电控制的干扰，并已制定了测量方法的标准。用RIV表来检测局放的测量线路与脉冲电流直测法的测量电路相似。此外，还可以利用一个接收线圈来接收由于局放而发出的电磁波，对于不同测试对象和不同的环境条件，选频放大器可以选择不同的中心频率（从几万赫兹到几十万赫兹），以获得最大的信噪比。这种方法已被用于检查电机线棒和没有屏蔽层的长电缆的局放部位。
光测法
光测法利用局放产生的光辐射进行检测。在变压器油中，各种放电发出的光波长不同，研究表明通常在500～700mm之间。在实验室利用光测法来分析局放特征及绝缘劣化等方面已经取得了很大进展，但是由于光测法设备复杂昂贵、灵敏度低，且需要被检测物质对光是透明的，因而在实际中无法应用。
射频检测法
利用罗果夫斯基线圈从变压器中性点处测取信号，测量的信号频率可以达到3万千赫兹，大大提高了局放的测量频率，同时测试系统安装方便，检测设备不改变电力系统的运行方式。但对于三相电力变压器，得到的信号是三相局放信号的总和，无法进行分辨，且信号易受外界干扰。随着数字滤波技术的发展，射频检测法在局放在线检测中得到了较广泛的应用。
高压设备局放检测的发展方向
随着科技的发展，特别是信号分析技术如神经网络、指纹分析、专家系统、模糊诊断和分形等都越来越多地应用到变压器局放检测中，对通过脉冲电流法按照IEC270标准测量得到数据，进行模式识别和绝缘寿命评估，推动了局放检测技术的发展。超高频检测方法从一开始就是从数字化技术起步的，通过将成功的传统方法移植到超高频检测之中，实现局放的连续在线监测和自动识别的研究正在取得快速的进展，上述超高频法存在的问题是目前很多相关研究单位需要解决的课题。笔者认为，任何一种方法都有一定的应用范围，有些问题它可以解决，有一些则不能解决。当前通信技术的发展使人们充分认识到，在线监测是个跨学科、综合性的研究领域，多种方法相结合，综合运行目前各种技术和知识，构建统一的、综合的在线监测平台，将是未来局放在线监测的发展方向。
目前，超高频方法的研究也面临着一些问题，由于测量机理与脉冲电流法不同，因此无法进行视在放电量的标定，而目前大多数工程人员已经习惯于通过视在放电量来反映局放的严重程度，IEC规定有关局放的变压器产品出厂标准中，其指标也是通过局放量的阈值来规定的。目前的研究表明，即使在局放源到传感器之间的传播路径不变的情况下，脉冲电流法的视在局放量与超高频方法所测得的脉冲信号幅值之间也没有确定的对应关系，这就更加大了应用该方法进行局放定量的难度；此外，由于变压器内部绝缘结构的复杂性，局放产生的电磁波在内部的传播将存在大量的散射、折反射以及衰减，因而传播特性研究和局放源定位工作将注定是难度很大而且充满挑战的。

中等规模生物质气化发电技术(项目推荐）
项目简介：
生物质气化发电技术是洁净利用生物质能的有效方法之一，它可以在不产生污染的情况下把生物质能转化为电能，达到从低品位能源获取高品位能源的目的，是最有前途的可再生能源技术之一。 因地制宜地利用丰富的生物质资源，建立分散、独立的离网或并网生物质分布式电站不仅可以弥补电力供应的不足，而且可以有效减少环境污染和温室气体排放，所以它也是一种重要的环保技术。
以农业废弃物和木材废弃物为主的生物质资源分布分散，收集和运输困难，不适合采用大规模燃烧技术，而中等规模的生物质气化发电技术（400—6000kW）在发展中国家具有独特的优势，也具备进入市场竞争的条件。中国科学院广州能源研究所研究开发的中等规模生物质气化发电技术达到了同类技术的国际先进水平，性价比处于国际领先水平，该技术共申请国家专利9项，已在中国、台湾和东南亚等国家推广应用，取得了显著的经济、社会和环境效益。生物质气化发电技术先后获得“九五”国家重点科技攻关计划优秀成果奖、广东省科技进步二等奖、上海国际工业博览会银奖、广东省优秀专利奖。2005年10月，在由联合国教科文组织发起的全球可再生能源领域最具投资价值的十大领先技术评选中该技术获得“蓝天奖”，再一次证明了生物质气化发电技术在国际上的影响力。
适用范围及应用条件：
该生物质气化发电技术应用范围广，灵活性好，根据用户不同需要，发电规模可选择在200-5000kW之间。用于处理碾米厂的谷壳，家具厂、人造板厂和造纸厂的木屑、边角料、树皮，为工厂提供电力，也适用于处理林场及农场的枝桠材、秸杆、稻草、稻壳等，为缺电农村地区和企业供电。同时，由于该项目属于环保技术，对消除污染，减少CO2的排放有重要的意义，有条件享受国家政府的相关优惠政策，有很好的市场前景和巨大的推广潜力。
主要技术性能及指标：
生物质气化发电技术采用循环流化床气化炉，把生物质废弃物，包括木料、秸秆、稻草、甘蔗渣等转换为可燃气体。这些可燃气体经过除尘除焦等净化工序后，再送到气体内燃机进行发电。为进一步提高系统效率，可利用气化系统和内燃机产生的余热，通过余热锅炉和蒸汽轮机实现联合循环发电。
该技术主要特点如下：
(1)采用循环流化床气化炉为燃气发生装置，利用气体内燃机代替燃气轮机，采用简单可靠的燃气净化方法。整个系统具有原料适应性好，处理规模大，负荷适应能力强，发电效率高等特点；
(2)采用新型专利技术，有效解决了燃气净化中的难题；采用特种菌种和好氧、厌氧相结合的方法处理焦油污水，实现气化发电系统中焦油污水循环利用；
(3)建立的5MW生物质气化及联合循环发电优化系统示范工程，克服了传统IGCC技术在发展中国家利用的限制，大大降低了技术难度和系统成本，设备全部国产化。
这些特点保证了气化发电系统的综合性能稳定可靠，单位投资和运行成本都较低的特点，系统达到以下技术经济指标：
以原料价格200元/吨计，简单生物质气化发电系统（400－3000kW）发电效率达到16－20％，单位投资：4000－4500元/kW，单位原料耗量：1.35kg/kWh，发电运行成本：0.35-0.45元/kWh；联合循环生物质气化发电系统（5MW）发电效率达28%，单位投资：6500元/千瓦，单位原料耗量1kg/kWh，发电运行成本<0.35元/ kWh。
已应用情况：
在全面分析市场需求的情况下，成功开发了400kW到5000kW的系列生物质气化发电装置，提高了整个技术的成套性和实用性，为推广应用奠定了良好的基础。自2000以来，该技术在中国、台湾和东南亚国家推广，已经成为国际上应用最多的中小型生物质气化发电系统。目前已签订和在建生物质气化发电项目共32项，总装机容量34 MW，累计合同额达8021.82万元，间接经济效益3400万元，新增产值 1.02亿元，取得了显著的经济效益；年减排CO2 约27.5万吨，环境效益显著。
该技术的推广应用为根本解决中国农村普遍存在的而又始终无法根治的“秸秆问题”提供了有效的利用途径。例如：一个3000kW的生物质发电站，年处理秸秆约2万吨，相当于2万亩的秸秆。电站以200元/吨的价格向农民收购秸秆，每亩地可增加产出50-100元；电站可解决90－150人的就业机会；生物质发电直接成本中的秸秆成本和人工成本约为0.35-0.4元/度电，直接转化为当地农民收入。如果每个县建设5万kW的生物质电站，每年可为农民增收1亿多元，其推广应用的社会效益非常显著。
已具备的推广应用条件：

生物质气化发电技术是洁净利用生物质能的有效方法之一，它可以在不产生污染的情况下把生物质能转化为电能，达到从低品位能源获取高品位能源的目的，是最有前途的可再生能源技术之一。 因地制宜地利用丰富的生物质资源，建立分散、独立的离网或并网生物质分布式电站不仅可以弥补电力供应的不足，而且可以有效减少环境污染和温室气体排放，所以它也是一种重要的环保技术。
以农业废弃物和木材废弃物为主的生物质资源分布分散，收集和运输困难，不适合采用大规模燃烧技术，而中等规模的生物质气化发电技术（400—6000kW）在发展中国家具有独特的优势，也具备进入市场竞争的条件。中国科学院广州能源研究所研究开发的中等规模生物质气化发电技术达到了同类技术的国际先进水平，性价比处于国际领先水平，该技术共申请国家专利9项，已在中国、台湾和东南亚等国家推广应用，取得了显著的经济、社会和环境效益。生物质气化发电技术先后获得“九五”国家重点科技攻关计划优秀成果奖、广东省科技进步二等奖、上海国际工业博览会银奖、广东省优秀专利奖。2005年10月，在由联合国教科文组织发起的全球可再生能源领域最具投资价值的十大领先技术评选中该技术获得“蓝天奖”，再一次证明了生物质气化发电技术在国际上的影响力。
适用范围及应用条件：
该生物质气化发电技术应用范围广，灵活性好，根据用户不同需要，发电规模可选择在200-5000kW之间。用于处理碾米厂的谷壳，家具厂、人造板厂和造纸厂的木屑、边角料、树皮，为工厂提供电力，也适用于处理林场及农场的枝桠材、秸杆、稻草、稻壳等，为缺电农村地区和企业供电。同时，由于该项目属于环保技术，对消除污染，减少CO2的排放有重要的意义，有条件享受国家政府的相关优惠政策，有很好的市场前景和巨大的推广潜力。
主要技术性能及指标：
生物质气化发电技术采用循环流化床气化炉，把生物质废弃物，包括木料、秸秆、稻草、甘蔗渣等转换为可燃气体。这些可燃气体经过除尘除焦等净化工序后，再送到气体内燃机进行发电。为进一步提高系统效率，可利用气化系统和内燃机产生的余热，通过余热锅炉和蒸汽轮机实现联合循环发电。
该技术主要特点如下：
(1)采用循环流化床气化炉为燃气发生装置，利用气体内燃机代替燃气轮机，采用简单可靠的燃气净化方法。整个系统具有原料适应性好，处理规模大，负荷适应能力强，发电效率高等特点；
(2)采用新型专利技术，有效解决了燃气净化中的难题；采用特种菌种和好氧、厌氧相结合的方法处理焦油污水，实现气化发电系统中焦油污水循环利用；
(3)建立的5MW生物质气化及联合循环发电优化系统示范工程，克服了传统IGCC技术在发展中国家利用的限制，大大降低了技术难度和系统成本，设备全部国产化。
这些特点保证了气化发电系统的综合性能稳定可靠，单位投资和运行成本都较低的特点，系统达到以下技术经济指标：
以原料价格200元/吨计，简单生物质气化发电系统（400－3000kW）发电效率达到16－20％，单位投资：4000－4500元/kW，单位原料耗量：1.35kg/kWh，发电运行成本：0.35-0.45元/kWh；联合循环生物质气化发电系统（5MW）发电效率达28%，单位投资：6500元/千瓦，单位原料耗量1kg/kWh，发电运行成本<0.35元/ kWh。
已应用情况：
在全面分析市场需求的情况下，成功开发了400kW到5000kW的系列生物质气化发电装置，提高了整个技术的成套性和实用性，为推广应用奠定了良好的基础。自2000以来，该技术在中国、台湾和东南亚国家推广，已经成为国际上应用最多的中小型生物质气化发电系统。目前已签订和在建生物质气化发电项目共32项，总装机容量34 MW，累计合同额达8021.82万元，间接经济效益3400万元，新增产值 1.02亿元，取得了显著的经济效益；年减排CO2 约27.5万吨，环境效益显著。
该技术的推广应用为根本解决中国农村普遍存在的而又始终无法根治的“秸秆问题”提供了有效的利用途径。例如：一个3000kW的生物质发电站，年处理秸秆约2万吨，相当于2万亩的秸秆。电站以200元/吨的价格向农民收购秸秆，每亩地可增加产出50-100元；电站可解决90－150人的就业机会；生物质发电直接成本中的秸秆成本和人工成本约为0.35-0.4元/度电，直接转化为当地农民收入。如果每个县建设5万kW的生物质电站，每年可为农民增收1亿多元，其推广应用的社会效益非常显著。
