电气设备功率问题

例如,汽车发动机的速就是他的频率,比如怠速500转/分钟,加速换档3000转/分钟,换算成8个频率.3Hz和50Hz。可见转速越高,发动机功率越大。

同样,在相同的频率下,发动机越大,输出功率越大,这就是为什么柴油机比汽油大,大柴油机可以驱动公交卡车和其他重型汽车。

同样,电机(或所有旋转机械)需要小,输出功率大,只有一种方法来提高速度,这就是为什么交流频率不能太低,因为我们需要小但大功率的电机。

变频空调也是如此。空调压缩机的输出功率是通过改变交流电的频率来控制的。总之,功率和频率在一定范围内是正相关的。

再说频率高怎么样?比如定在400Hz怎么样?

二是线路和设备损耗增加,二是发电机转速过快。

首先,耗。输电线路、变电站设备和电气设备都有电抗。电抗与频率成正比。频率越高,电抗越大,消耗的无功率越大,能传的有功率越少。目前50Hz输电线路的电约0.电阻约为4欧姆的10倍,如果提高ABB DSA系列模块DSAI133A 3BSE018290R1、DSAI130D 3BSE003127R1、DSAI130、DSA401-38G、DSA1208-28A、DSAI146-AI145ABB DSA系列模块DSAI133A 3BSE018290R1到400Hz,那电抗将是3.2欧姆,电阻约80倍。降低电抗是提高高压输电线路输电功率的关键。

与电抗相对应的是容抗,与频率成反比。频率越高,容抗越小,线路泄漏电流越大。如果频率高,线路的泄漏电流也会增加。

另一个问题是发电机的速度。目前的发电机组基本上是单级机,即一对磁极。发送50Hz电,转子每分钟转速3000转。当汽车发动机转速达到3000转时,你可以清楚地感觉到发动机在振动。当到6000或7000转时,你会觉得发动机几乎跳出了发动机罩。

汽车发动机仍然如此,更不用说一个重达100吨的实心铁疙瘩转子和汽轮机了,这也是电厂噪音大的原因。每分钟转3000转100吨钢转子并不容易。如果频率再高三四倍,估计发电机会飞出工厂。

如此重的转子具有相当大的惯性,这也是电力系统被称为惯性系统,可以保持安全稳定运行的前提。这也是风电和太阳能间歇性电源挑战传统电源的原因。

因为风景的变化ABB DSA系列模块DSAI133A 3BSE018290R1、DSAI130D 3BSE003127R1、DSAI130、DSA401-38G、DSA1208-28A、DSAI146-AI145ABB DSA系列模块DSAI133A 3BSE018290R1很快ABB DSA系列模块DSAI133A 3BSE018290R1、DSAI130D 3BSE003127R1、DSAI130、DSA401-38G、DSA1208-28A、DSAI146-AI145ABB DSA系列模块DSAI133A 3BSE018290R1,几十吨重的转子由于巨大的惯性,要减少出力或增加出力的速度很慢(爬坡率的概念),跟不上风电和光伏发电的变化,所以有时不得不弃风和弃光。

由此可见

频率不能太低的原因:变压器能效高,电机能小功率大。

频率不能过高的原因:ABB DSA系列模块DSAI133A 3BSE018290R1、DSAI130D 3BSE003127R1、DSAI130、DSA401-38G、DSA1208-28A、DSAI146-AI145ABB DSA系列模块DSAI133A 3BABB DSA系列模块DSAI133A 3BSE018290R1、DSAI130D 3BSE003127R1、DSAI130、DSA401-38G、DSA1208-28A、DSAI146-AI145ABB DSA系列模块DSAI133A 3BSE018290R1SE018290R线路和设备损耗小,发电机转速不必过高。

Industrial control refers to industrial automation control, which is mainly realized by the combination of electronics, electricity, machinery and software. That is industrial control, or factory automation control. It mainly refers to the use of computer technology, microelectronics technology and electrical means to make the production and manufacturing process of the factory more automated, efficient, accurate, controllable and visible.

Industrial control computer is a general term for tools that use bus structure to detect and control the production process and its electromechanical equipment and process equipment. It has important computer attributes and characteristics, such as computer CPU, hard disk, memory, peripherals and interfaces, real-time operating system, control network and protocol, computing power, friendly man-machine interface, etc. The main categories of industrial computers include IPC (PC bus industrial computer), PLC (programmable control system), DCS (distributed control system), FCS (Fieldbus System) and CNC (numerical control system). Everyone who studies electronics knows that PLC is a very important device and a relatively difficult technology. It is a digital operation electronic system specially designed for application in the industrial environment. It is the basis for realizing industrial automation and Internet of things control. It has a very broad application prospect in the future.

PLC technology originated in the United States

PLC technology originated in the United States. General Motors of the United States was the first to apply PLC. In the 1960s, when they adjusted the factory production line, they found that the relay and contactor control system was difficult to modify, large in size, noisy, inconvenient to maintain and poor in reliability. Subsequently, the American digital equipment company developed the first programmable controller, which was tested on the production line of General Motors with remarkable results. Later, PLC technology was carried forward in Japan and Europe, and programmable controllers were successfully developed in Japan and Germany. In 1974, China also began to study programmable controllers and widely used in various fields.

PLC first replaced the mechanical switch device, and then the function of PLC gradually replaced the relay control board. Modern PLC has more functions, and its purpose extends from single process control to the control and monitoring of the whole manufacturing system.

Application of PLC technology in industrial automation, Internet of things control and other fields

At present, PLC technology is widely used in industrial automation, automotive electronics, transportation, Internet of things control and other industries. Its role in these fields can be roughly divided into four categories.

1、 Used to realize various motion control

PLC controller is a digital electronic device with microprocessor. It is a digital logic controller used for automatic control. It can load control instructions into memory at any time for storage and execution. The programmable controller is composed of internal CPU, instruction and data memory, input and output unit, power module, digital analog and other units. PLC controller can be used for the control of circular motion or linear motion. Nowadays, almost all the main PLC controller products have motion control function. It is used in various machinery, machine tools, robots, elevators and other occasions.

In terms of control mechanism configuration, in the early days, it was directly used for switching value i/o module to connect position sensor and actuator. Now, special motion control module is generally used, such as single axis or multi axis position control module that can drive stepper motor or servo motor.

2、 Realize industrial process control

As an industrial control computer, PLC controller can compile various control algorithm programs to complete closed-loop control. In industrial process control, PLC is mainly used for closed-loop control of analog parameters such as temperature, pressure, flow and so on. Large and medium-sized PLCs have PID modules. PID regulation is a regulation method commonly used in general closed-loop control systems. At present, many small PLC controllers also have this function module.

3、 Realize relevant data processing

Modern PLC controller has the functions of mathematical operation, data transmission and conversion, and can complete data collection, analysis and processing; These data can be compared with the reference value stored in the memory to complete certain control operations, and can also be transmitted to other intelligent devices by using the communication function. In large-scale control systems, such as unmanned flexible manufacturing system, PLC controller is one of the core components.

4、 PLC communication and Internet of things

As the general trend of industrial Internet of things, the related technologies of PLC communication and Internet of things will be popular in the future. General PLC controller communication includes communication between PLC controllers and communication between PLC controller and other intelligent devices. With the development of industrial control automation, all PLC controller manufacturers attach great importance to the communication function of PLC controller, and have launched their own network systems. New PLC controllers have communication interfaces, which is very convenient for communication.

PLC technology has great potential in the industrial control and Internet of things markets

Three characteristics of PLC technology in the future

1. Miniaturization and integration are getting higher and higher: with the requirements of the market for miniaturization and integration, PLC technology is more integrated into industrial, automotive, communication and other products. The characteristics of PLC products are control and data processing. While meeting the functions, the technological requirements are more refined.

2. Intelligent PLC technology: with the development of AI technology, more products are endowed with intelligent functions, PLC is no exception. For example, the intelligent i/o module of PLC applied in industrial control and the intelligent temperature control module of automobile, etc., there will be more application scenarios of intelligent PLC technology in the future.

3. Diversified PLC technology: including PLC related programming languages and tools. With the deepening of application scenarios, one or several programming languages cannot achieve all functions, customized PLC products will increase, and PLC modular technology will also increase.
