Description

A system to realize the automatic generation and operation of ATP power system simulation calculation model

technical field

The invention relates to the technical field of power system simulation calculation, in particular to a system for realizing automatic generation and operation of an ATP power system simulation calculation model.

Background technique

Simulation calculation is a necessary technical means for power system planning and design, operation scheduling and accident analysis. Accurate and reasonable simulation calculation model is the premise and basis for effective simulation calculation. ATP software is a fast, accurate and easy-to-use power system simulator for various power system design and verification. It can be widely used in electromagnetic transient process, lightning protection design of overhead lines, high voltage/ultra high voltage transmission system operation and Research on control and other aspects is a common analysis tool in the field of transient simulation.

However, with the continuous expansion of the grid scale, the continuous increase in the number of system components, and the continuous increase in the difficulty of solving problems in simulation calculations, the complexity of simulation calculation models has been increased, and the professional technical level of model compilers has also been raised. higher requirement. At present, most of the simulation calculation models are still compiled manually by operators. Due to the large network scale and the large number of components, the model compilation workload is heavy, there are many repetitive tasks, the probability of errors is high, and it is difficult to find. At the same time, manual compilation is an off-line compilation method, which cannot reflect the real-time network operation status, and the resulting model has poor timeliness and low reliability. It is very difficult and unrealistic to rely on the operation personnel of the power department to complete the analysis of the simulation calculation results of the power system. Therefore, the current manual compilation of simulation calculation models can no longer adapt to this new situation, and even the task of model compilation cannot be completed. In order to solve the above problems, although there is currently a method to automatically complete the simulation calculation model compilation according to the network topology and component parameters, because the algorithm used in the simulation calculation process is self-developed, its functions are extremely limited, and its reliability is significantly lower than that of ATP Such widely used simulation calculation software; or when generating the simulation calculation model, the compiler still needs to manually collect the necessary data and convert it into a specific format, which also has the problems of heavy workload and high error probability.

Therefore, if the simulation calculation model that can be invoked by the simulation calculation software can be automatically generated directly from various raw data of the power system and automatically cycled as needed, the model compilation process can be greatly simplified, the difficulty of model compilation can be reduced, and the accuracy of the model can be improved. It can also enable staff to focus on the subsequent analysis process and improve the efficiency of simulation calculations.

Detailed ways

In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be introduced below in conjunction with the embodiments of the present invention and the accompanying drawings.

According to the original data required for compiling the ATP simulation calculation model and the format of the ATP simulation calculation model file, the present invention automatically compiles and generates the ATP simulation calculation main model file, and automatically generates the overhead line simulation calculation that can be called by the ATP simulation calculation main model file model file. According to the main model file of ATP simulation calculation and the simulation calculation model file of overhead line, the corresponding data card file is automatically written and generated, and various data cards are connected to automatically generate an executable ATP simulation calculation model program. Automatically run the executable ATP simulation calculation model program, read the simulation results, judge whether the simulation requirements are met according to the simulation results, end if the simulation results are met, and output the simulation results. If the requirements are not met, the model parameters will be adjusted according to the preset model parameter adjustment algorithm, and the ATP simulation calculation model program will be automatically regenerated and executed automatically until the simulation results meet the simulation requirements.

As shown in Figure 1, a system of the present invention that realizes the automatic generation and operation of an ATP power system simulation calculation model includes a data format processing module 11, a simulation calculation model master file generation module 12, a data card generation module 13, and a simulation calculation model A program generation module 14 , a simulation calculation model program automatic execution module 15 , a simulation calculation result judgment module 16 , a simulation calculation model parameter adjustment module 17 , and a simulation calculation result output module 18 . Wherein the data format processing module 11 is connected with the simulation calculation model master file generation module 12; the simulation calculation model master file generation module 12 is connected with the data card generation module 13; the data card generation module 13 is connected with the simulation calculation model program generation module 14; the simulation calculation The model program generation module 14 is connected with the automatic execution module 15 of the simulation calculation model program; the automatic execution module 15 of the simulation calculation model program is connected with the simulation calculation result judgment module 16; the simulation calculation result judgment module 16 is connected with the simulation calculation model parameter adjustment module 17; The calculation model parameter adjustment module 17 is connected with the simulation calculation model master file generation module 12 and the simulation calculation result output module 18 .

The data format processing module 11 is used to store the original data of the power system (including power supply parameters, grounding parameters, tower parameters, lightning current parameters, overhead line parameters, etc.) in the database. For different types of simulations, the required parameters are different. The same, for example, lightning data is needed in the simulation of lightning fault, but in the simulation of non-lightning fault, there is no lightning parameter), converted into the format required by the main file of the ATP simulation calculation model, due to ATP’s requirements for the model file format Very strict, the length of characters occupied by different types of component data is different, and the requirements for the arrangement of characters are very strict, so it is necessary to process the data format and convert it into characters of a certain length. When the length of the data is too long, it needs to be converted into scientific notation and saved in the form of a string. When the length of the data is not enough, you need to add spaces in front and convert it into a string. For example, the length of parameters of power components is mostly six characters, so it is necessary to read the parameters in the EXCEL table and convert them into six characters in length. If the data in the EXCEL table is not enough for six characters, you need to add spaces in front. If it exceeds six digits, it needs to be converted into the form of scientific notation, and then when generating the ATP code, directly output the data in the form of six characters. For example: in ATP, the length of the power supply data is generally 10, if the original data is '123456789', the length of the data is 9, no more than 10 bits, then after the data processing module 11, the output is '123456789', in the original A space is added in front of the data. If the original data is '111122223333', the length of the data is 12 bits, which exceeds 12 bits, so the output result after processing is '1.11122E12', that is, the output is converted into an exponential form for output.

The simulation calculation model master file generation module 12 is used to generate the ATP simulation calculation model master file according to the conversion result of the data format processing module 11 . During specific implementation, it can be realized by compiling the texts of the components involved in each simulation calculation model in the master file.

The data card generation module 13 is used to generate each data card, for example, for the power supply element, read the data processed by the data format processing module 11, and then write the power supply data card. The main data cards include: initial data card, TACS data card, MODEL data card, branch data card, switch data card, power supply data card, output data card and blank data card. The English name of TACS is Transient Analysis of Control Systems, which is used for instantaneous analysis of control systems; MODEL is a custom model, which is convenient for writing custom components with specific functions according to the actual needs of users. The writing methods of these data cards can be obtained from the help manual of the ATP simulation software. Example: A typical power data card looks like this:

/SOURCE

C < n 1><><Ampl.><Freq.><Phase/T0><A1><T1><TSTART><TSTOP>

14X00S1A 0179629.248 50. 30. -1. 1.

14X00S1B 0179629.248 50. -90. -1. 1.

14X00S1C 0179629.248 50. 150. -1. 1.

14X00S2A 0179629.248 50. 300. -1. 1.

14X00S2B 0179629.248 50. 180. -1. 1.

14X00S2C 0179629.248 50. 420. -1. 1.

Among them, C indicates the comment, n1 is the name of the node, here is the parameter of the power supply, so the first column below is the name of the power supply node, Ampl is the amplitude, here is the voltage source amplitude, and Freq is Frequency, Phase/T0 represents the phase, A1 and T1 are for lightning current or lightning voltage, A1 represents the amplitude of lightning current (voltage) at T1 time, TSTART and TSTOP represent the start time and end time, start Use -1 for the time to indicate that the power supply has started to function at the beginning of the simulation.

It can be seen that the power data card mainly consists of parameters such as power node name, power type (voltage source and current source), power amplitude, power frequency, and initial phase.

The simulation calculation model program generation module 14 is used to connect various data cards obtained by the data card generation module 13 (generally according to the starting data card, TACS data card, MODEL data card, branch data card, switch data card, power supply data card) Card, output data card and blank data card are connected sequentially, and the data card that is not available in the specific implementation can be skipped, for example, if there is no custom component, then there is no MODEL data card), and an executable ATP simulation calculation model program is generated, such as : In order to generate an ATP program, it is first necessary to generate a file with the suffix ATP, and its generated code is:

fid=fopen('auto_atp.atp','w','native');(fid is a handle to generate a file, handle information will be used when operating on the file, fopen is a function to open a file in MATLAB, If the file does not exist, a corresponding file will be created, 'w' means to operate the file in the form of writing, 'native' is the writing format, which means writing in the default format, which can be omitted)

This code means to generate the file auto_atp.atp.

In order to write other data cards, just add the following code at the beginning of other data cards.

fid=fopen('auto_atp.atp','a');

This code means to continue writing after the file auto_atp.atp. Among them, a indicates subsequent writing, that is, if the auto_atp file exists, continue writing, instead of erasing the original auto_atp content and rewriting.

The simulation calculation model program automatic execution module 15 is used for automatically running the ATP simulation calculation model program generated by the simulation calculation model program generation module 14 to obtain the simulation result file. This can be achieved by calling the runATP.exe program that comes with the ATP simulation software. For example, using the MATLAB programming language to automatically run the simulation calculation model program named Example.atp, the corresponding command is: system (example.atp ).

The simulation calculation result judging module 16 automatically reads the simulation calculation data from the simulation result file obtained by the simulation calculation model program automatic execution module 15, and processes the data to determine whether insulation breakdown occurs. The ATP simulation calculation results are saved in the LIS file. The format of the LIS file can be obtained from the help manual of the ATP simulation software. Therefore, read the relevant data in the LIS file, and judge whether each phase breaks down by processing the read data. For example, in the case of three-phase simulation, if the data of the three phases A, B and C in the LIS are all 0 within the simulation time, it means that no breakdown occurs, and the output is [0 00]. If the data of the two phases of A, B and C in the LIS During the simulation time, it is all 0, and the data of phase C is not all 0 during the simulation time, it means that the phase C is broken down, and the output is [0 0 1], 1 means that the breakdown occurs, and 0 means that there is no breakdown.

The simulation calculation model parameter adjustment module 17 adjusts the simulation model parameters according to the output of the simulation calculation result judging module 16 . The adjustment strategy is preset. First, the simulation calculation model parameter adjustment module 17 judges whether the simulation calculation results meet the preset requirements, and if the simulation calculation results meet the requirements, the results are output and displayed by the simulation calculation result output module 18 . If the requirements are not met, the simulation model parameters can be adjusted according to the difference between the simulation calculation result and the target value, and the new parameters are sent to the simulation calculation model master file generation module 12, and the simulation calculation model is automatically generated and the operating system is re-executed. According to the difference between the simulation calculation results and the target value, the adjustment of the simulation model parameters can be realized by existing mature optimization methods, such as golden section, simple linear or neural network, particle swarm optimization algorithm, etc. During specific implementation, the working process of the simulation calculation model parameter adjustment module 17 can be to judge whether the simulation calculation results meet the preset requirements, and if the requirements are met, the simulation calculation result output module 18 will be ordered to output and display the current simulation calculation results, Otherwise, adjust the simulation model parameters according to the difference between the simulation calculation result and the target value, send new parameters to the simulation calculation model master file generation module 12, and order the simulation calculation model master file generation module 12 to regenerate the ATP simulation calculation model master file, simulation calculation model master file generation module 12, data card generation module 13, simulation calculation model program generation module 14, simulation calculation model program automatic execution module 15, simulation calculation result judgment module 16, simulation calculation model parameter adjustment module 17 will be based on The new ATP simulation calculation model master file also carries on the follow-up work.

The simulation calculation result output module 18 is used to output the simulation calculation results that meet the requirements.

In summary, when generating the ATP simulation calculation model, the user only needs to pre-specify simple information such as a certain area of the power system that needs to be simulated (that is, the parameters of the components in these areas), and the software interface can be used to automatically generate the ATP simulation calculation model. The required simulation calculation model does not require manual intervention in the entire generation process, which reduces the difficulty of model compilation; the data for model compilation comes from the analysis of the original database, which improves the accuracy of model compilation; the use of computers can complete model compilation tasks and improve improve the efficiency of modeling.

It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive, so the present invention is not limited to the embodiments described in the specific implementation, and those skilled in the art according to the technical solutions of the present invention Other obtained implementation modes also belong to the protection scope of the present invention.
