Problems solved by technology
Each power system manufacturer has its own grid modeling methods, but due to differences in developers or system versions, there are great differences in the structure of the created models, graphics or databases, forming a certain degree of "information islands", resulting in It becomes very difficult to share information and achieve some degree of interoperability between different systems

Embodiment Construction
[0074] The power plant voltage control simulation method using the public information model for data interaction proposed by the present invention, its flow chart is as follows figure 1 shown, including the following steps:
[0075] (1) At the beginning of each grid power flow calculation, the grid verification system finds the established grid model in the grid verification system according to the name of the automatic voltage control substation device of the power plant, and generates the primary equipment model of the current power plant i. The process is as follows:
[0076] (1-1) From the station model of the grid model, obtain the record Si={S} of the current power plant i, (Si is the number of the power plant) and store Si in the data buffer;
[0077] (1-2) In the voltage base value model of the power grid model, obtain all voltage base values VT={VTj,j=1,...,n1} belonging to the current power plant i, where n1 is all voltage base values of the current power plant i...

The invention relates to a power plant voltage control simulation method for data interaction using a public information model, and belongs to the technical field of automatic voltage control of electric power systems. First, the CIM model file of the primary equipment model of the power plant is formed according to the power grid model of the verification system, and downloaded to the AVC sub-station of the power plant. The sub-station establishes the calculation model of the AVC sub-station of the power plant according to the verification system model, and automatically completes the preparation for verification. During the verification process, when each control cycle comes, the AVC substation device receiving verification receives the operating status of the power plant and the AVC voltage adjustment command from the verification system through the CIM measurement file, and sends the calculated reactive power adjustment amount of the generator to In the verification system; by analyzing the CIM measurement files, the power flow is calculated after the reactive power adjustment of the simulated unit to obtain the new operating state of the power grid, thereby realizing the continuous closed-loop verification process. The method realizes the plug-and-play of the AVC substation technical performance verification platform of the power plant, and significantly reduces the manual maintenance work in the verification process of the AVC substation of the power plant.
Description
technical field [0001] The invention relates to a power plant voltage control simulation method for data interaction using a public information model, and belongs to the technical field of automatic voltage control of electric power systems. Background technique [0002] Automatic voltage control (hereinafter referred to as AVC, Automatic Voltage Control) system is an important means to achieve grid security (increase voltage stability margin), economy (reduce network loss), and high-quality (increase voltage qualification rate) operation. The AVC system architecture is based on the grid energy management system (hereinafter referred to as EMS), which can use the real-time operation data of the grid to scientifically make the best reactive power and voltage adjustment scheme from the perspective of overall grid optimization, and automatically send it to power plants, substations and subordinates The power grid dispatching organization executes. The AVC system takes voltage ...
