We are about to graduate, we will start a round of job hunting experience, learning power system and its automation, I feel that the burden on their shoulders is really not light, the responsibility borne by students of this specialty is really heavy as Mount Taishan, because of this, I also feel very proud and proud of it, also I hope that I can live up to the trust of teachers and society, and really contribute to the power system to their greatest strength.
The study of the power system for so long, but also learned a lot about the current situation of the power system, then I will first say that I learned the current situation of the power system and its automation, as well as my feelings.
The electric power system is a system for the production and consumption of electric energy composed of transmission and use of electricity and other links. Its function is to convert the primary energy of nature into electric energy through power generation power plant (mainly including boilers, turbines, generators and power plant auxiliary production system, etc.), and then through the transmission, substation system and distribution system to supply electric energy to the load center, through a variety of equipment and then converted into different forms of energy such as power, heat, light, and so on, to serve for the regional economy and people's life. As most of the power points and load centers are in different areas, and can not be stored in large quantities, so its production, transmission, distribution and consumption are completed at the same time, and in the same geographical area organically composed of a whole, electric energy production must always maintain a balance with consumption. Therefore, the centralized development and decentralized use of electric energy, as well as the continuous supply of electric energy and random changes in the load, the structure and operation of the power system constraints. Accordingly, in order to realize its function, the power system needs to set up corresponding information and control system in each link and at different levels, so as to measure, regulate, control, protect, communicate and dispatch the process of production and transmission of electric energy, and ensure that the users can obtain safe, economic and high-quality electric energy.
The establishment of a reasonable structure of the large-scale power system not only facilitates the centralized management of power production and consumption, unified scheduling and distribution, reducing the total installed capacity, saving power facilities investment, and is conducive to the rational development and utilization of regional energy resources, to a greater extent to meet the growing needs of the national economy of the region's electricity. Power system construction is often an important part of national and regional national economic development planning.
Power system automation is our power system has been striving for the direction of development, which includes: the automation of power generation control (AGC has been achieved, still need to be developed), the automation of power dispatch (with online trend monitoring, fault simulation of the integrated program as well as the SCADA system to achieve the automation of the distribution network, the hottest integrated automation of the substation that is the construction of integrated since the station, to achieve better unmanned duty. Better unmanned shift. DTS that the dispatcher training simulation system for the dispatcher to learn to provide a convenient), distribution automation (DAS has been realized, yet to be developed).
According to the production and distribution process of electric energy, power system automation includes grid scheduling automation, thermal power plant automation, integrated automation of hydroelectric power plants, automatic transmission system of power system information, power system anti-accident automation devices, power supply system automation, automation of electric power industry management system and so on 7 aspects, and form a hierarchical hierarchical automation system (see figure). Regional dispatching center, regional substations and regional power plants form the lowest level; the middle level consists of provincial (municipal) dispatching centers, hub substations and directly under the power plants, and the highest level is formed by the general dispatching center. And in each level, power plants, substations, distribution networks, etc. constitute multiple levels of control.
I study is the power system and its automation, it is the combination of the two a higher level of specialization, therefore, with my own requirements I do not dare to relax at all times, in the study of professional knowledge, can better use professional knowledge on the basis of the country's electric power system to make their own contribution to my ultimate goal. However, in today's society, undergraduate graduate students abound, as the study of power systems and automation of college students, facing the pressure can be imagined, so, want to contribute to their own strength, must find a good platform, a platform that allows them to play, which is to say that my future intentions.
In general, due to the national power shortage since 2000, so power generation has become a very hot industry, exactly what will be hot to when to see the national policy (after all, this is a state must monopolize the industry), of course, such a meat and potatoes plus state-owned enterprises have caused the growth of the whole society's relationship with the growth of the family, due to the number of sons and daughters, the relationship with the family is not the same each year, so the power generation Looking for work each year between the big difference, and each province, region are very big difference, this year the market is good, but can not guarantee that next year is also a bull market. Therefore, the first thing to do is to try to find out this year's market, the so-called know yourself and know your enemy.
There are some, such as Dongfang Electric, Nanrui and so on. Nanrui is still a very powerful enterprise, now a lot of domestic electrical equipment are Nanrui products, in many areas can compete with Nanrui very few companies, such as in many projects do not have to bidding (because it can achieve this level of only one of its own), but Nanjing Nanrui and Shenzhen Nanrui technology into a competitive situation, Shenzhen Nanrui technology location in Shenzhen Science and Technology Park, the office environment is still good! The office environment is still good, and the large office empty nearly half of the position, see its lack of people.
My hometown is Cangzhou Huanghua port, which is a coal energy output port, is the second largest port after the Qinhuangdao coal transportation east. Cangzhou Guohua Power Plant is located in Huanghua Harbor. The construction of Guohua Cangdong Power Plant is a national key project with a total installed capacity of 4.8 million kilowatts, which is the largest thermal power plant in North China. For me, this is a good opportunity, a good platform for my own development, I hope I can go to Guohua Power Plant to study and work, contribute their own share of power for the country's power development.
There is another thing that touched me particularly. This year, the south of China suffered a 50-year snowstorm, and it happened that one of my relatives went to school in Changsha, Hunan Province. Before he came back to Changsha, there were two big snowstorms in Changsha, and he told me that before he came back to Changsha, the power supply there would be cut off from time to time. Later, listening to the news, indeed, Hunan is the hardest-hit area of the snowstorm, power facilities have been seriously damaged, the country suffered heavy losses, which is exactly a revelation to our power system students, to try to do their jobs, to ensure that the people's normal life, the most a qualified power system practitioners.
