Chapter 11 Distribution Network Automation
Tian Yusheng is back. This is the understanding of people who know Tian Yusheng, and then they realize that this kid is developed, he can go directly to General Manager Fu, this guy is really developed.
"How? How was this trip to the sea city? Fu Xin asked with a smile.
Tian Yusheng replied excitedly: "Very good, really, Mr. Fu, really good, I met my classmate's father, he is really the chairman of offshore electric, he also took me to a factory of offshore electric to see, it is true, Chairman Xu Dong told me that he is very interested in the west-to-east power transmission project, and now I am looking forward to your cordial and friendly exchanges with him in the past, and the two sides exchange some opinions, and then he will report the project to the above, and ask for the approval of the above." ”
"Oh? Xu Dong, the chairman of Offshore Electric, wants to see me? Fu Xin was a little stunned, this Xu Dong's movements were very fast. I can't help but sigh from the bottom of my heart, there is still a leader with courage, and now many leaders in China are actually pursuing the golden mean, putting stability first, and there are few people who dare to take risks casually.
For example, the chief designer, this one is walking in the right position of leading China in reform and opening up, so in the future, he will get the title of a great man!
"Yes, Chairman Xu Dong wants to see you, and he also told me that I want you to do it as soon as possible, the sooner the better!" Tian Yusheng emphasized.
At this moment, Fu Xin didn't believe it, looked at Tian Yusheng suspiciously, and asked: "Comrade Tian Yusheng, this can't be made up by you, then Chairman Xu Dong should have only told you that he wanted to see me, but he didn't say that he was in a hurry to see me!" ”
"Pay the total. It's true, you are the leader. How dare I deceive you! Chairman Xu Dong is eagerly looking forward to your meeting with him, which is true! Tian Yusheng said anxiously. I'm afraid Fu Xin doesn't believe him.
"Well, I'll trust you for now." Fu Xin nodded, and then muttered to himself, "It's just that this Xu Dong is so anxious to see me, why is this?" No, how can such a thing be decided so quickly? ”
Tian Yusheng stood aside and did not speak, although he clearly heard Fu Xin's muttering. But he's not stupid, he still knows what he can and can't say. Talking nonsense will cause you to get angry.
……
Fu Xin still followed Tian Yusheng to Sea City, but when he arrived in Sea City, Fu Xin temporarily decided to go to the guest house for two days first, think carefully about Xu Dong's intentions, and then go to see him.
As for the internal meeting of the Ministry of Posts and Telecommunications, this is still early, even if you stay in Sea City for half a month. It's okay to go back to Xunyang and then to Beijing.
So, Li Boxian, Nie Hongqi and Tian Yusheng, who came with Fu Xin, as well as Fu Xin. Four people stayed at the guest house.
"Comrade Yusheng, do you have any relatives here?" Fu Xin discussed Xu Dong's intentions with Li Boxian at the guest house, and saw Nie Hongqi open the door. Tian Yusheng was carrying a lot of pastries and gifts, so he began to ask suspiciously.
Tian Yusheng shook his head and said, "No." It's a very good professor I knew in the past, and I haven't seen each other for seven or eight years. I don't know if it's still there. Last time, I came in a hurry, and I was in a hurry to go back, and I didn't look for it, didn't this time just give you two days? You also said I could move around freely, so I went out and bought some gifts and was going to check them out later. ”
"Absent? Isn't it a lot of age? Fu Xin then asked.
Tian Yusheng crossed his fingers and replied: "I was fifty-six or seventy when I was taught, and now I am in my sixties and nearly seventy years old, and the old man's health is not very good." ”
"What does he do for a long time?" Fu Xin continued to ask curiously.
"It is mainly engaged in distribution network research. In the study of distribution network automation system, he has a deep accumulation, a lot of experience, when I studied with him, he was very good to me, treat me as his children. Tian Yusheng said with a bit of nostalgia.
"Oh, is that so?" Fu Xin heard that it is a high distribution network uh research, but also has a deep accumulation in the research of distribution network automation, which is now very lacking in power equipment experts Huaxing, it is really a small happy event, if this can be dug up for experts, he is great!
Fu Xinyi jumped off the bed, pulled Li Boxian, called Nie Hongqi, and said, "Boxian, Hongqi, let's go, let's go visit this old expert." ”
Tian Yusheng hesitated, looked at Fu Xin with embarrassment and said: "Mr. Fu, I don't know if he is still alive now, and also, when I followed him to study, I didn't go to his house, when we separated, he only left a home address for me, it's been seven or eight years, and I don't know if he still lives there. ”
Fu Xin is the kind of guy who is full of energy when he sees talents, at this time he said disapprovingly: "Fight in the air, just fly in the air, anyway, idle is idle, it's really boring to guess here, we are not the roundworms in Xu Dong's stomach can know what he thinks in his heart, let's go, I should go and visit this sea city, this sea city, I haven't been careful for some years." It just so happened that I asked Hongqi to drive us together. ”
In order to make things easier, Fu Xin borrowed a jeep from Liu Yi, who was doing business in Sea City, and used it to travel to save trouble. In fact, at that time, Liu Yi wanted Fu Xin and them to live in his house, but Fu Xin politely refused, because Liu Yi's house couldn't accommodate the four of them.
And it's not very convenient, Liu Yi's place is really a long distance away from offshore electric. Therefore, Fu Xin's four people still chose to live in a guest house, but Liu Yi didn't let Fu Xin go out of the money for this accommodation. He had already rushed to hand it over.
Tian Yusheng has almost figured out Fu Xin's temper, this guy is definitely eager to seek talent, so he didn't shirk it anymore. A few people began to go out, and Fu Xin helped Tian Yusheng take a large bag of gifts and put them in the trunk of the jeep. Then Fu Xin, who hadn't touched a jeep for a long time, drove Tian Yusheng and others to a workers' dormitory area in Puyang District, Haihai City.
On the way. Tian Yusheng carefully explained to Fu Xin and the three of them the situation of the old professor they were going to visit, and the professor's name was Sun Zhenglu. In fact, he is just a visiting professor at the Institute of Offshore Electric Power, and his identity is a researcher at an electrical research institute in Offshore City. In the distribution network, especially in the distribution network automation system research, very experienced, very powerful, very capable.
The so-called distribution network automation system refers to the use of modern electronics, communications, computers and network technology, the distribution network structure information, distribution network operation real-time information and offline information, user information, equipment information, geographic information integration, constitute a complete automation management system, to achieve the distribution network in normal operation and accident monitoring, protection, control and management.
In the era before Fu Xin's crossing, the development of the distribution network automation system was already very powerful. Its application and implementation mainly have the following modes:
The first is the feeder automation system (FA) based on the mutual cooperation of automatic switchgear, and its main equipment is a recloser and a sectionalizer, which does not need to build a communication network and a master station computer system, and its main function is to realize fault isolation and restore power supply in a sound area through the cooperation of automatic switchgear in the event of a failure.
The distribution automation technology at this stage is represented by the recloser and voltage time type sectionalizer coordination mode and the recloser and recloser coordination mode. In fact, this implementation mode only realizes the feeder automation function of the distribution automation system to achieve the purpose of improving the reliability of power supply.
The second is a real-time application system based on communication network, feeder terminal unit and background computer network, which is generally composed of master station system, terminal equipment and communication system, mainly including power distribution operation monitoring (DSCADA), feeder automation (FA), power distribution advanced application (DPAS), power distribution simulation training (DDTS) and other functions. When the distribution network is in normal operation, it can play the role of monitoring the operation status of the distribution network and changing the operation mode by remote control. When the fault is detected, it can be detected in time, and the dispatcher isolates the fault area and restores the power supply of the sound area through remote control. This implementation mode is one of the mainstream modes of distribution automation system, which is also the mainstream mode of distribution automation system built in China in the future.
The third is the distribution automation system that has no real-time application and only distribution management function, which mainly realizes the management function of distribution automation. It mainly includes automatic mapping/equipment management/geographic information system (AM/FM/GIS), power distribution work management (DWM), power outage management system (OMS), fault complaint management (TCM), etc.
The main starting point of this implementation model is to improve the management efficiency of the distribution network, and there is no obvious effect on the reliability of power supply. There are also very few applications in China.
The fourth is a distribution automation system that integrates real-time application and management application, which can cover the whole process of dispatching, operation and production of the entire distribution network. Customer service is also supported. It mainly includes distribution operation monitoring (DSCADA), feeder automation (FA), power distribution advanced application (DPAS), power distribution simulation training (DDTS), automatic mapping/equipment management/geographic information system (AM/FM/GIS), distribution work management (DWM), power outage management system (OMS), fault complaint management (TCM), load management (LM), demand side management (DSM) and other functions.
Generally, it is integrated by the application of several systems, such as DSCADA, FA, DPAS, DDTS, etc. in the above functions, which belong to distribution network scheduling automation. AM/FM/GIS belongs to enterprise asset management, DWM and OMS belong to power supply production management, TCM belongs to power customer service, and LM and DSM belong to load management.
Compared with dispatching automation and substation automation, distribution network automation started late, especially in China, distribution network automation actually only exists in the laboratory, and the practical application has not yet started. If you exclude the butterfly that Fu Xin crosses, the automation of the domestic distribution network will not be until after 1998, with the large-scale development of urban and rural power grid construction and transformation, will set off the first round of distribution network automation technology pilot and application in many provinces and municipalities directly under the central government.
