Telecom and SCADA between electrical substations and a study of the structure and how to communicate in DPLC DG CCHP, CHP
- Introduction: به because of the extensiveness of the network of interconnected production and transmission in the electricity industry and the scattering of the stations in the points, sometimes out of reach, launching and roughing telecommunication systems of the basic needs of the industry, the electricity industry. Land uses major telecommunication in the electric power industry include : 1 - the transfer of information and send commands auto-protective to isolate sections of injured and defective in the shortest time and avoid the extensiveness of the minor accidents to the entire network and the Prevention of possible accidents. 2 - transfer information collected from posts and power plants to centers of control and transfer commands to the control from control centers to the stations. 3 - coordination of operation and communicate between departments, staff and operational through the network, telephone, independent power. سیستم communication used in the network, telecom, power industry, included wireless, etc. microwave oven, ETC., PLC, ETC., DTS., the fiber optic system, and switching. - PLC system telecommunication is that of lines of high pressure at the frequency of 40 to 400 kHz for the transfer of messages, telecommunication uses. - DTS network dedicated Hot Line Telephone دیسپاچینگ can be. - cable OPGWدر power transmission lines, instead of the Earth Wire for data transfer with the volume and security of the most used. سیستمPower Line Carrier is one of the modern methods of data transfer, which is its acronym PLC, but not the controller logic programmable, but power transmission lines. توسعه resources, production, transmission and distribution of electrical energy need urgently to the existence of a network between key points power system, like the Centers of production, conversion, decision-making and distribution, mostly at intervals far apart, actually have been there. Transmission lines can be used to send the waves of frequency above the carrier information in the system of telecommunication used. System that for this species the transfer of information used in the tool, \\\"transmission carrier wave, the information on the system pressure, strong\\\" or PLC is called. موارد under the necessity of creating a network Telecommunications PLC to clear the track: 1 - network, telecom, public respond to the communication needs of the direction of the effective operation of the network, strong pressure is not. 2 - تبادلاطلاعات between the Centers of دیسپاچینگ and other پستهاتوسط a شبکهمخابراتی مطمئنو dedicated, from the necessities of such centers can be. 3 - use a comprehensive network of telecommunication, posts can to protective equipment equipped with a return that makes the ability to trust more and effective operation of the network can be. 4 - the lack of a network dedicated to. the weakness of communication via network, telecommunications, telecommunications company, the lack of access the majority of posts located outside the city, to the lines of communication PTT problems are that if there is a network, make sure the sides have to be exploited more efficiently from the network it creates. با pay attention to the tips above, the direction of Upland, the bugs listed and operation of the grid, can be used سیستمهایPLCچنین networks of Telecommunication for use in networks power supply design. استفاده from the PLC instead of other communication systems, such as cable, telephone, etc. radio waves and microwaves, and ... has benefits that can include : 1 - due to the insignificant being, the drop signal carries information in each area. the Centers of production and distribution of electrical energy, usually at intervals away from each other واقعند can be straight by Ka ...

Temperature and humidity control of the server room
There are many server room temperature and humidity control devices and there are many providers in Iran, some of them are manufacturers and some are just product sellers, but what is more important is which system is really effective at the cost of it. and there is no impression that buying it was wrong from the beginning. But why should it be wrong to buy a server room protection system? Please pay attention to the following points. \r\n\r\n1- If the intelligent control of the server room that is purchased is unstable or gives false warnings\r\n2- If the intelligent system of the server room that is purchased sends a late or late warning \r\n3- If the intelligent monitoring of the server room that is purchased is disabled in times of danger and does not have the ability to send an alert.\r\n4- If the intelligent temperature controller of the server room that is purchased does not have the necessary quality to protect the server room\r\n5- If the intelligent automation of the server room that is purchased is provided by a company that does not have much experience in control and automation.\r\n6- If the intelligent control of the server room is not designed internally and we have to spend a lot of time for maintenance \r\n\r\n[Types of server room sensors]\r\nThe above and other such cases can cause irreparable problems for the manager of the server room, so the employer finally comes to the conclusion that he made a wrong choice, but this choice cannot be reversed and cannot damage the server room or The data of the server room was compensated and the smart control system that was purchased cannot be returned.\r\nTherefore, the solution to prevent these incidents from happening is to carefully check and choose a reliable and safe smart system. You can find an example of it in the link below.\r\n \r\nhttps://pishrans.com/src2-2\r\nresume \r\nhttps://pishrans.com/projects1\r\nPhotos of projects\r\nhttps://pishrans.com/photo-project
