    Tian Yusheng is back.  This was the understanding of people who knew Tian Yusheng, and then they realized that this guy was so prosperous that he could go directly to General Manager Fu. This guy was really prosperous.  "How was it? How was your trip to Sea City?" Fu Xin asked with a smile.  Tian Yusheng replied excitedly: "Very good, really good, Mr. Fu, really good. I met the father of my classmate. He is really the chairman of Haihai Electric. He also took me to visit a factory of Haihai Electric."  , it¡¯s true. Chairman Xu Dong told me that he is very interested in the west-to-east power transmission project. Now he is looking forward to you having a cordial and friendly exchange with him. The two parties will exchange some opinions, and then he will report the project.  Go up and ask for approval from above. "Oh? Xu Dong, the chairman of Offshore Electric, wants to see me?" Fu Xin was a little stunned. Xu Dong moved very quickly.  I can¡¯t help but sigh from the bottom of my heart, there is still a courageous leader. Many leaders in the country now actually pursue the golden mean and put stability first. There are few who dare to take risks casually. Of course, there are those who dare to take risks and succeed.  , then the future will be limitless.  For example, the chief architect, this person is leading China in the right position of reform and opening up, so in the future, he will get the title of a great man of the generation!  "Yes, Chairman Xu Dong wants to see you. He also told me that he wants you to meet as soon as possible. The sooner the better!" Tian Yusheng emphasized.  At this time, Fu Xin didn't believe it anymore. He looked at Tian Yusheng doubtfully and asked, "Comrade Tian Yusheng, you couldn't have made this up, right? Chairman Xu Dong should have just told you that he wanted to see you."  "I didn't say you were anxious to see me!" "Mr. Fu, it's true. You are the leader. How dare I lie to you? It's absolutely true that Chairman Xu Dong is eager to see you.  Ah!" Tian Yusheng said anxiously, fearing that Fu Xin wouldn't believe him.  "Okay, I believe you for the time being." Fu Xin nodded, and then murmured to himself, "It's just that Xu Dong is so anxious to see me, what is he doing? It shouldn't be, how can such a thing happen?  "You made your decision so quickly?" Tian Yusheng stood aside and said nothing. Although he clearly heard Fu Xin's mumbling, he was not an idiot. He still knew what to say and what not to say.  Talking nonsense can lead to anger.  ¡­ Fu Xin still followed Tian Yusheng to Sea City, but when he arrived at Sea City, Fu Xin made a temporary decision to stay in a guest house for two days to think clearly about Xu Dong¡¯s intentions before going to see him.  As for the internal meeting of the Ministry of Posts and Telecommunications, it is still early. Even if you stay in Haicheng for half a month, return to Xunyang, and then go to Beijing, it will be fine.  So, Li Boxian, Nie Hongqi, Tian Yusheng, and Fu Xin, who came with Fu Xin, lived in the guest house.  "Comrade Yusheng, do you have any relatives here?" Fu Xin was discussing Xu Dong's intentions with Li Boxian at the guest house. When he saw Nie Hongqi opening the door and Tian Yusheng carrying a lot of cakes, gifts and so on, he began to ask doubtfully  asked.  Tian Yusheng shook his head and said: "No, he is a very good professor I met in the past. I haven't seen him for seven or eight years, and I don't know if he is still there. I came in a hurry last time and was in a hurry to go back. I didn't look for him this time.  Didn't you give me two days, Mr. Fu, so I went out to buy some gifts and went over to see you later? "Are you very old?"  Xin then asked.  Tian Yusheng answered with his fingers: "When he taught me, he was fifty-six or seventy years old. Now he is over sixty and almost seventy years old. The old man's health is not very good." "What is his main job?" Fu  Xin continued to ask curiously.  "Mainly engaged in research on distribution network. He has a deep accumulation and a lot of experience in the research of distribution network automation system. When I studied with him, he was very kind to me and treated me as his son or daughter.  Treat it the same way," Tian Yusheng said with a hint of nostalgia.  "Oh, is that so?" Fu Xin heard that he was engaged in high-level research on distribution network, and he also had a deep accumulation in the research on distribution network automation. This is really useful for Huaxing, which currently lacks experts in power equipment.  It's a small happy event. It would be great if we could recruit this expert!  Fu Xin jumped out of bed, pulled Li Boxian with him, called Nie Hongqi, and said: "Bo Xian, Hongqi, let's go, let's go visit this old expert." Tian Yusheng hesitated, rather embarrassed.  Looking at Fu Xin, he said: "Mr. Fu, I don't even know if he is still alive. Also, when I was studying with him, I never went to his home. When we separated, he only left one family behind.  Give me his address. It's been seven or eight years. I don't know if he still lives inHere, if you don¡¯t do it well, you¡¯ll get nothing.  " Fu Xin is the kind of guy who gets full of energy when seeing talents. At this time, he said disapprovingly: "If you are short, just be short. Anyway, you are idle. It is really boring to guess here all the time. We are not here anymore.  It's not like the roundworm in Xu Dong's stomach can know what he is thinking in his heart. Let's go, it's time to go shopping in this sea city. I haven't visited this sea city carefully in some years.  Just in time, I asked Hongqi to drive us there.  " In order to facilitate things, Fu Xin borrowed a jeep from Liu Yi, who was doing business in Haizhou City, to avoid trouble. In fact, Liu Yi wanted Fu Xin and the others to live in his house at that time, but Fu Xin and the others lived in his house.  Xin declined politely. It was true that Liu Yi's house could not accommodate the four grown men, and it was not very convenient. Liu Yi's place was quite far away from Haihai Electric, so the four of them still chose to live there.  Guest house, but Liu Yi refused to let Fu Xin pay for it. He had already rushed to hand it over. Tian Yusheng had almost figured out Fu Xin's temper. This guy was definitely hungry for talents.  So there was no further excuse. Fu Xin and others helped Tian Yusheng carry the large and small packages of gifts and put them in the trunk of the jeep. Then Fu Xin, who had not touched the jeep for a long time, drove the car himself.  Tian Yusheng and others drove to a workers' dormitory area in Puyang District, Shanghai City. On the way, Tian Yusheng carefully explained to Fu Xin and the others the situation of the old professor they were going to visit. The professor's name was Sun Zhenglu.  He is just a visiting professor at the Maritime Electric Power College. He is a researcher at an electrical research institute in Maritime City. He is very experienced, powerful and capable in the research of distribution networks, especially distribution network automation systems.  The distribution network automation system refers to the use of modern electronics, communications, computers and network technologies to integrate distribution network structure information, distribution network operation real-time and offline information, user information, equipment information, and geographical information to form a complete  The automation management system realizes the monitoring, protection, control and management of the distribution network under normal operation and accident conditions. By the time before Fu Xin traveled, the development of the distribution network automation system was already very impressive, and its applications were already very impressive.  There are mainly the following modes of implementation: The first is a feeder automation system (FA) based on the cooperation of automated switchgear. Its main equipment is a recloser and a segmenter. It does not require the construction of a communication network and a master station computer system.  The main function is to realize fault isolation and restore power supply to sound areas through the cooperation of automated switching equipment in the event of a fault. The distribution automation technology at this stage adopts the cooperation mode of recloser and voltage-time segmenter and the cooperation mode of recloser and recloser.  Representative. This implementation mode actually only realizes the feeder automation function of the distribution automation system to achieve the purpose of improving power supply reliability. The second is a real-time application system based on the communication network, feeder terminal unit and background computer network.  It consists of main station system, terminal equipment and communication system, and mainly includes distribution operation monitoring (DSCADA), feeder automation (FA), distribution advanced application (DPAS), distribution simulation training (DDTS) and other functions in the distribution network.  During normal operation, it can monitor the operating status of the distribution network and change the operating mode remotely. When a fault occurs, it can be detected in time, and the dispatcher can isolate the fault area and restore power supply to the healthy area through remote control. This implementation mode is distribution automation.  One of the mainstream modes of the system, this is also the mainstream mode of the distribution automation system built in China in the future.  The third type is a distribution automation system that has no real-time application and only has distribution management functions. It mainly realizes the management functions of distribution automation, including automatic mapping/equipment management/geographic information system (AM/FM/GIS), distribution  Work management (DWM), 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 it has no obvious effect on the reliability of power supply. Even at the time before Fuxin Crossing, this model had very few domestic applications.  The fourth type is a distribution automation system that integrates real-time applications and management applications. It can cover the entire process of dispatching, operation, and production of the entire distribution network, and also supports customer service.  Mainly includes distribution operation monitoring (DSCADA), feeder automation (FA), distribution advanced application (DPAS), distribution simulation training (DDTS), automatic mapping/equipment management/geographic information system (AM/FM/GIS),  Distribution work management (DWM), outage management system (OMS), fault complaint management (TCM), load management (LM), demand side management (DSM) and other functions.  It is generally integrated by the applications of several systems. For example, DSCADA, FA, DPAS, DDTS, etc. among the above functions belong to distribution network dispatching automation, AM/FM/GIS belongs to enterprise asset management, DWM and OMS belong to power supply production management, and TCM belongs to users.  Electric customer service, LM and DSM belong to load management, through thisThe application integration of these different systems achieves a complete power distribution management system integrating real-time and management.  Compared with dispatch automation and substation automation, distribution network automation started late. Especially in my country, distribution network automation only exists in laboratories, and practical applications have not yet started.  If we exclude the butterfly that traveled through "Fu Xin", the domestic distribution network automation will actually not start its second wave in many provinces and municipalities in China until after 1998, with the large-scale construction and transformation of urban and rural power grids.  There is an upsurge in the pilot and application of distribution network automation technology.  (To be continued.
