Electric Power Systems 电力系统
The modern society depends on the electricity supply more heavily than ever before. 现代社会的电力供应依赖于更多地比以往任何时候。 It can not be imagined what the world should be if the electricity supply were interrupted all over the world. 它无法想象的世界应该是什么,如果电力供应中断了世界各地。 Electric power systems (or electric energy systems), providing electricity to the modern society, have become indispensable components of the instrial world. 电力系统(或电力能源系统),提供电力到现代社会,已成为不可缺少的组成部分产业界的。
The first complete electric power system (comprising a generator, cable, fuse, meter, and loads) was built by Thomas Edison – the historic Pearl Street Station in New York City which began operation in September 1882. 第一个完整的电力系统(包括发电机,电缆,熔断器,计量,并加载)的托马斯爱迪生所建-站纽约市珍珠街的历史始于1882年9月运作。 This was a DC system consisting of a steam-engine-driven DC generator supplying power to 59 customers within an area roughly 1.5 km in radius. The load, which consisted entirely of incandescent lamps, was supplied at 110 V through an underground cable system. 这是一个半径直流系统组成的一个蒸汽发动机驱动的直流发电机面积约1.5公里至59供电范围内的客户。负载,其中包括完全的白炽灯,为V提供110通过地下电缆系统。 Within a few years similar systems were in operation in most large cities throughout the world. With the development of motors by Frank Sprague in 1884, motor loads were added to such systems. This was the beginning of what would develop into one of the largest instries in the world. In spite of the initial widespread use of DC systems, they were almost completely superseded by AC systems. By 1886, the limitations of DC systems were becoming increasingly apparent. They could deliver power only a short distance from generators.
在一个类似的系统在大多数大城市在世界各地运行数年。随着马达的弗兰克斯普拉格发展在1884年,电机负载被添加到这些系统。这是什么开始发展成为世界上最大的产业之一。在最初的直流系统广泛使用尽管如此,他们几乎完全被空调系统所取代。到1886年,直流系统的局限性也日益明显。他们可以提供功率只有很短的距离从发电机。
To keep transmission power losses ( I 2 R ) and voltage drops to acceptable levels, voltage levels had to be high for long-distance power transmission. Such high voltages were not acceptable for generation and consumption of power; therefore, a convenient means for voltage transformation became a necessity. 为了保持发射功率损失(我2 R)和电压下降到可接受的水平,电压等级,必须长途输电高。如此高的电压不发电和电力消耗可以接受的,因此,电压转换成为一个方便的手段的必要性。
The development of the transformer and AC transmission by L. Gaulard and JD Gibbs of Paris, France, led to AC electric power systems. 在发展的变压器,法国和交流输电由L.巴黎戈拉尔和JD吉布斯导致交流电力系统。
In 1889, the first AC transmission line in North America was put into operation in Oregon between Willamette Falls and Portland. 1889年,第一次在北美交流传输线将在俄勒冈州波特兰之间威拉梅特大瀑布和实施。
It was a single-phase line transmitting power at 4,000 V over a distance of 21 km. With the development of polyphase systems by Nikola Tesla, the AC system became even more attractive. By 1888, Tesla held several patents on AC motors, generators, transformers, and transmission systems. Westinghouse bought the patents to these early inventions, and they formed the basis of the present-day AC systems.这是一个单相线路传输功率为4,000公里,超过21 V系统的距离。随着交流的发展多相系统由尼古拉特斯拉,成为更具吸引力的。通过1888年,特斯拉举行交流多项专利电动机,发电机,变压器和输电系统。西屋公司购买了这些早期的发明专利,并形成了系统的基础,现在的交流。
In the 1890s, there was considerable controversy over whether the electric utility instry should be standardized on DC or AC. By the turn of the century, the AC system had won out over the DC system for the following reasons: 在19世纪90年代,有很大的争议或交流电力行业是否应该统一于直流。到了世纪之交的,在交流系统赢得了原因出在下面的直流系统为:
(1)Voltage levels can be easily transformed in AC systems, thus providing the flexibility for use of different voltages for generation, transmission, and consumption. (1)电压水平可以很容易地改变了空调系统,从而提供了传输的灵活性,发电用不同的电压和消费。
(2)AC generators are much simpler than DC generators. (2)交流发电机简单得多比直流发电机。
(3)AC motors are much simpler and cheaper than DC motors. (三)交流电机和电机便宜简单得多,比直流。
The first three-phase line in North America went into operation in 1893——a 2,300 V, 12 km line in southern California. 前三个阶段的美国北线投产于1893年- 1 2300五,南加州12公里路线研究。 In the early period of AC power transmission, frequency was not standardized. 在电力传输初期交流,频率不规范。 Many different frequencies were in use: 25, 50, 60, 125, and 133 Hz. 有许多不同频率的使用:25,50,60,125,和133赫兹。 This poses a problem for interconnection. Eventually 60 Hz was adopted as standard in North America, although 50 Hz was used in many other countries. 这对互连的问题。最后60赫兹标准获得通过,成为美国在北美,虽然是50赫兹在许多其他国家使用。
The increasing need for transmitting large amounts of power over longer distance created an incentive to use progressively high voltage levels. To avoid the proliferation of an unlimited number of voltages, the instry has standardized voltage levels. In USA, the standards are 115, 138, 161, and 230 kV for the high voltage (HV) class, and 345, 500 and 765 kV for the extra-high voltage (EHV) class. In China, the voltage levels in use are 10, 35, 110 for HV class, and 220, 330 (only in Northwest China) and 500 kV for EHV class . 较长的距离越来越需要大量的电力传输多激励他们逐步使用高压的水平。为了避免电压增殖数量无限,业界标准电压水平。在美国,标准是115,138, 161,和230千伏的高电压(高压)类,345,500和765千伏级的特高电压(超高压)。在中国,各级使用电压为10,35,110级高压, 220,中国330(仅在西北)和500千伏超高压类。
The first 750 kVtransmission line will be built in the near future in Northwest China. 第一个750 kVtransmission线将建在不久的将来在中国西北地区。
With the development of the AC/DC converting equipment, high voltage DC (HVDC) transmission systems have become more attractive and economical in special situations. 随着交流的发展/直流转换设备,高压直流高压直流(HVDC)传输系统已经成为更具吸引力的经济和情况特殊。 The HVDC transmission can be used for transmission of large blocks of power over long distance, and providing an asynchronous link between systems where AC interconnection would be impractical because of system stability consideration or because nominal frequencies of the systems are different. 在高压直流输电可用于输电块以上的大长途电话,并提供不同系统间的异步连接在AC联网系统将是不切实际的,因为稳定考虑,或因标称频率的系统。
The basic requirement to a power system is to provide an uninterrupted energy supply to customers with acceptable voltages and frequency. 基本要求到电源系统是提供一个不间断的能源供应,以客户可接受的电压和频率。 Because electricity can not be massively stored under a simple and economic way, the proction and consumption of electricity must be done simultaneously. A fault or misoperation in any stages of a power system may possibly result in interruption of electricity supply to the customers. 由于电力无法大量储存在一个简单的方法和经济,电力的生产和消费必须同时进行。系统的故障或误操作的权力在任何阶段可能导致电力供应中断给客户。 Therefore, a normal continuous operation of the power system to provide a reliable power supply to the customers is of paramount importance. 因此,一个正常的电力系统连续运行的,提供可靠的电力供应给客户的重要性是至关重要的。
Power system stability may be broadly defined as the property of a power system that enables it to remain in a state of operating equilibrium under normal operating conditions and to regain an acceptable state of equilibrium after being subjected to a disturbance. 电力系统稳定,可广泛定义为干扰财产的权力系统,可继续经营的状态下正常运行的平衡条件和后向遭受恢复一个可以接受的平衡状态。
Instability in a power system may be manifested in many different ways depending on the system configuration and operating mode. 在电力系统的不稳定可能会表现在经营方式和多种不同的方式取决于系统配置。
Traditionally, the stability problem has been one of maintaining synchronous operation. Since power systems rely on synchronous machines for generation of electrical power, a necessary condition for satisfactory system operation is that all synchronous machines remain in synchronism or, colloquially "in step". This aspect of stability is influenced by the dynamics of generator rotor angles and power-angle relationships, and then referred to " rotor angle stability ". 传统上,稳定性问题一直是一个保持同步运行。由于电力系统的发电电力,一个令人满意的系统运行的必要条件是,依靠同步电机同步电机都留在同步或通俗的“步骤”。这一方面是受稳定的发电机转子的动态角度和功角的关系,然后提到“转子角稳定”。

In this winding system, we use Mitsubishi A series PLC as master station
PLC because it has the characteristic of quick response and great ability of
information processing. It is used to control the behaviors of the total
winding system together with FX series PLCs of winding and unwinding
system. The operating actions of the system and the sequence of these
actions were edited beforehand into the control program by the designer. The
control program sets a series of operations of the winding system, which tells
the PLCs how to control a system. The current states of all sensors or
actuators are saved as an array of input, output or flag signals in the PLC
memory. Therefore, the PLC program is the basis of monitoring in a PLC
controlled manufacturing system.
The programming method used is the ladder diagram method. The PLC
system provides a design environment in the form of software tools running
on a host computer terminal which allows ladder diagrams to be developed,
verified, tested, and diagnosed. First, the high-level program is written in
diagrams. Then, the ladder diagram is converted into binary instruction
codes so that they can be stored in random-access memory (RAM) or
erasable programmable read-only memory (EPROM). Each successive
instruction is decoded and executed by the CPU. Thefimctionof the CPU is to control the operation of memory and I/O devices and to process data
according to the program. Each input and output connection point on a PLC
has an address used to identify the I/O bit. The method for the direct
representation of data associated with the inputs, outputs, and memory is
based on the fact that the PLC memory is organized into three regions: input
image memory, output image memory, and internal memory。

The main advantage of this concept is that
the consecutive controller is able to control disturbances of humidifying arrangement directly, because the dew point measurement of the humidifier has got a very short response time compared with the quite longer response time of the furnace dew point. This is caused by bigger time delays of the measurement and the delay time of the process gas to come into the furnace.
Analysis station for CO/CO2, H2 and O2ppm monitoring,
extracting method will be multiplexed sampling
An analysis station designed as a complete functional unit will be used for monitoring the composition of the atmosphere in the Furnace.
The analysis station will be a single-cabinet unit complete with analyzers, pumps, solenoid valves and control unit. In normal operation, the sample gas switchover system will switch cyclically between the different sample gases. The system can also be switched to nitrogen for purging or to a calibration gas; this is not part of the normal cycle.
The sample waste gas will be fed from the sampling probe on the furnace (with filter) to the analyser or sample gas treatment system through a sample gas line routed downwards. Sample gas from each sample gas point will be extracted by the main sample gas pump to the analyser station. The sample gas 'in measurement' will be switched to the measurement line from where an additional pump pumps it to the analysers. The sample gas lines will be made from acid-resistant plastic.
The multiplexing analysis system has following probes:
For CO/CO2 the system in an actual mode can be calibrated automatically every day using an in-built comparison probe. The calibration time is triggered using an internal period value, which can be changed manually. During calibration time no measurement values are available.
A particular feature will be to switch from multiplexing measuring mode to single mode, where a certain probe gas inlet can be measured continuously and vice versa.
