Description

Technical Field

[0001] The present invention relates to the field of substation process processing and systems, and in particular to a method and system for dynamically configuring process processing parameters in combination with the real-time status of a substation. Background Art

[0002] Smart substations mainly include smart high-voltage equipment and unified information platform for substations. Smart high-voltage equipment mainly includes smart transformers, smart high-voltage switchgear, electronic transformers, etc. Smart transformers are connected to the control system by communication optical fiber, which can timely grasp the status parameters and operation data of transformers. When the operation mode changes, the equipment decides whether to adjust the tap according to the voltage and power of the system; when there is a problem with the equipment, it will issue an early warning and provide status parameters, etc., which can reduce the operation and management costs, reduce hidden dangers, and improve the reliability of transformer operation to a certain extent. Smart high-voltage switchgear is a high-performance switchgear and control equipment equipped with electronic equipment, sensors and actuators, and has monitoring and diagnostic functions. Electronic transformers refer to pure optical fiber transformers, magneto-optical glass transformers, etc., which can effectively overcome the shortcomings of traditional electromagnetic transformers. The unified information platform of substations has two functions: one is the horizontal information sharing of the system, which is mainly manifested in the unification of information acquisition by various upper-level applications in the management system; the other is the standardization of vertical information of the system, which is mainly manifested in the transparency of each layer's support for its upper-level applications.

[0003] Intelligence means humanization, which means making the substation act like a person adjusting the volume. When the low-voltage load increases, the substation sends out electricity to meet the increased load. When the low-voltage load decreases, the amount of electricity sent by the substation decreases accordingly, ensuring energy saving.

[0004] Smart grid construction is a grid development mode adopted by China to adapt to the current and future social development of my country based on the characteristics of energy distribution and load consumption in my country. It has strong adaptability to the inclusion and transmission of various energy sources, especially large-scale wind power and solar power generation, and can achieve large-scale and efficient allocation of energy resources. Smart substation is one of the core platforms for realizing energy conversion and control in the construction of strong smart grid, and its prospects are still broad. By 2015, about 5,182 smart substations will be newly built, including about 19 new 750 kV smart substations, about 182 500 kV smart substations, about 60 330 kV smart substations, about 1,198 220 kV smart substations, and about 3,710 110 (66) kV smart substations; 64 500 kV, 18 330 kV, 320 220 kV, and 630 110 (66) kV substations will be renovated.

[0005] In smart substations, traditional cable wiring is no longer used in engineering, and is replaced by optical fiber cables. Highly integrated and low-power electronic components are widely used in various electronic devices. In addition, traditional oil-filled transformers have not escaped the fate of being eliminated, and electronic transformers have replaced them. Whether it is the improvement of various equipment or wiring methods, it has effectively reduced energy consumption and waste, not only reducing costs, but also effectively reducing the harm caused by electromagnetic, radiation and other pollution inside the substation to people and the environment, greatly improving the quality of the environment, optimizing the performance of the substation, and making its ability to protect the environment more significant.

[0006] One of the basic requirements of customers for electric energy is reliability. Smart substations are highly reliable. While meeting customer needs, they also achieve high-quality operation of the power grid. Because the substation is a system, it is easy to have a phenomenon of domino effect on the whole body. Therefore, the substation itself and all internal facilities have high reliability. Such characteristics also require the substation to have the function of detecting and managing faults. Only with this function can the occurrence of substation faults be effectively prevented, and the faults can be quickly handled after they occur, so that the working conditions in the substation are always kept in the best state.

[0007] According to the plan, the progress of newly built smart substations will maintain a relatively fast growth rate in the early stage, and the proportion of smart substation transformation will gradually increase in the later stage. As of the sixth batch of bidding in 2013, the number of smart substations tendered has reached about 3,600, which is basically in line with the planning expectations. However, the proportion of smart substations tendered in recent batches has decreased compared with the previous period. The main reasons are: the operation effect of the smart substations promoted by the State Grid in the early stage did not meet expectations; the manufacturing cost of smart substations decreased slowly, and the cost was still high; the State Grid is actively promoting the second-generation smart substation pilot project, which is expected to slow down the construction progress of existing smart substations and reduce the proportion of smart substations tendered. As the new generation of smart substation pilot projects are gradually put into operation, the proportion of smart substations tendered will continue to increase, and the construction progress will continue to accelerate.

[0008] However, existing smart substations can only analyze and alarm within a threshold when performing real-time monitoring and subsequent processing of equipment within the station. It is impossible to establish a huge database for long-term analysis, data processing and learning. In addition, during long-term operation, staff in the station need to monitor and observe the equipment status at all times, and the system cannot automatically repair and maintain common faults.

[0051] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0060] Data management and maintenance processing.

[0061] Real-time equipment status monitoring includes the following steps:

[0062] The monitoring system collects real-time operating data of each device and facility in the substation, detects the real-time temperature, voltage and current levels, circuit breaker status, etc. of the transformer, and ensures that the real-time temperature, voltage and current levels, and circuit breaker status of the transformer are operating in the best state. By installing temperature and humidity sensors and smoke detectors, the substation monitoring system monitors the environment and safety conditions of the substation in real time through temperature and humidity sensors and smoke detectors, maintains the stability of the substation, and promptly discovers potential safety hazards.

[0065] Transfer information to database for archival storage;

[0066] Provide a basis for subsequent data analysis and maintenance.

[0067] That is, the acquisition system of the substation automatically collects the real-time temperature, voltage and current levels, circuit breaker status and other information of the transformer in the substation during operation, records the real-time temperature, voltage and current levels, circuit breaker status and other information of the transformer as data, and transmits the data information to the database in the substation for archiving and storage. The substation has a huge database system, which records and stores data, and performs data analysis during the storage process, thereby serving as a basis for subsequent maintenance.

[0068] Abnormal state fault detection includes the following steps:

[0069] The substation monitoring system works all day and performs real-time detection on each device and line in the substation. By detecting the real-time transformer temperature, voltage and current levels, circuit breaker status, etc., and comparing the data with the preset normal range values, it can promptly identify abnormal conditions such as high transformer temperature, voltage overload, unstable current, etc.

[0075] That is, the monitoring system in the substation continuously monitors and measures the inside of the substation. After detecting that the status of a certain device or line exceeds the preset threshold, the monitoring system immediately sends out a warning signal to alarm. At the same time, the monitoring system troubleshoots the abnormal part, accurately locates the fault location to the specific equipment and line, and provides it to the maintenance personnel. The maintenance personnel quickly arrives at the location of the fault based on the provided information and maintains the abnormal equipment and lines at the fault location. At the same time, the monitoring system records the abnormality in the database and transmits data to the database. The database performs data analysis and transmits the analysis results back to the monitoring system. The monitoring system provides the analysis results to the maintenance personnel, who analyze the data provided to find out the cause of the fault, thereby shortening the subsequent repair time.

[0076] The remote control process includes the following steps:

[0077] The operation and maintenance personnel have the authority to remotely control the substation's monitoring system. They can use their authority to remotely control the equipment in the substation to repair faults.

[0081] By analyzing and learning a large amount of data, the monitoring system can propose suggestions for optimizing substation operations, such as load adjustment and energy-saving measures.

[0082] That is, the operation and maintenance personnel can set up the system of the substation. After the settings are completed, the system in the substation can automatically drive the rescue programs to deal with various problems in the substation according to the settings of the operation and maintenance personnel, and record the data of each fault during the processing and transmit it to the database. The database is in the process of continuous learning and evolution. After recording and analyzing the data many times, the database can simulate the situation when the fault occurs. After simulating the fault handling many times, the database simulates the best processing flow according to the processing structure, thereby proposing load adjustment, energy-saving measures and other source suggestions for optimizing the operation of the substation.

[0083] The data management and maintenance process includes the following steps:

[0084] The substation monitoring system is equipped with a powerful database that stores historical and real-time data for data backtracking and trend analysis;

[0085] The monitoring system automatically generates daily, monthly, and annual power consumption reports, equipment operation status reports, and other statistical reports based on management needs;

[0086] The monitoring system records all maintenance and repair activities and is used to track the maintenance history of the equipment and predict future maintenance needs.

[0087] To sum up, the advantages of the present invention are: the monitoring system of the substation can analyze and learn the data in the database and the real-time monitoring data, and continuously upgrade in the learning process to continuously optimize the monitoring system of the substation, and continuously analyze the data obtained from the monitoring to obtain trend analysis, maintenance needs analysis, etc. At the same time, the operation and maintenance personnel can remotely control the monitoring system of the substation, thereby realizing long-distance operation, improving the flexibility of operation and protection of the operation and maintenance personnel, and the monitoring system can be set to operate automatically, and can handle and solve problems by itself when dealing with common faults, thereby handling and solving faults as quickly as possible while reducing manual intervention.
