The electrical system can also supply power to equipment such as a nuclear power plant high-power motor, a 380V power motor, a downstream transformer, a downstream switchboard, an in-situ box and the like.

The professional electrical system simulation model consists of two parts, namely an electrical load model and a power distribution network model. The method comprises the following steps that information such as bus names, voltage levels, switch numbers, equipment names, rated power, rated current and the like is required to be acquired from design input when an electrical load model is established; the establishment of the distribution network model requires that the connection of the upstream and downstream voltage buses and the connection relation between main electrical equipment in the upstream and downstream voltage buses are obtained from the electrical single line diagram from top to bottom and from left to right.

The design information mainly concerned by establishing the electrical simulation model is as follows: the equipment code of the circuit breaker on the upstream incoming line of the system single line diagram, the upstream and downstream voltage grades of the circuit breaker and the system code of the incoming line power supply; the equipment code and voltage grade of the motor load on the load feeder line branch circuit; coding and voltage grade of the local box on the load feeder branch circuit; the type of contactor group of the control circuit of the load device, i.e., the type of control logic in the secondary wiring diagram, such as the low voltage contactor circuit CF1-CF2-CF3 of fig. 2-3; transformer equipment codes, contactor group equipment codes and upstream and downstream voltage grades on the branches of the downstream low-voltage distribution board; the device code of the charger on the direct current bus, the device code of the incoming and outgoing line breaker, the rated voltage of the direct current side and the rated voltage of the alternating current side; the device name of an inverter on a direct current bus, the device code of an incoming and outgoing line breaker, the rated voltage of a direct current side and the rated voltage of an alternating current side; the equipment name and rated capacity of the storage battery on the direct current bus; topology data information of the distribution network, namely, original topology connection relation representing the medium voltage distribution network, and the like.

In the past, an electrical system simulation model in a traditional mode verification platform is adopted in a nuclear power plant, generally, design input data such as a system single line diagram and a feeder line table are submitted by electrical specialties, an electrical simulation engineer manually establishes a distribution network topology model according to each single line diagram, and then data such as load equipment category, design power, design current and the like in a corresponding distribution feeder line table are filled into an electrical load model. The electrical systems of the nuclear power plant are numerous, and the method relying on manual modeling has the following technical problems that firstly, the labor cost is high, the professional level of an electrical simulation engineer limits the method, and errors are easy to occur. Secondly, the difference between the simulation drawing and the electrical single line diagram in appearance expression form is large, and a design verifier needs to spend longer time understanding the simulation drawing. And thirdly, separating the data transmission link between the design and the simulation modeling. Thereby seriously affecting the simulation modeling efficiency of the electrical system. Meanwhile, the integrated cooperation participation degree of the electrical major in the verification platform is low, so that the verification activity period is long and the efficiency is low. And the method is in conflict with the high-efficiency synergy advocated by the digital nuclear power plant and the intelligent design verification process.

Detailed Description

The invention is further described with reference to the following figures and detailed description.

Example one

As shown in fig. 1, the electrical simulation automatic modeling method of the present invention includes the following steps:

and S1, summarizing all design files related to electrical simulation, combing single line diagrams of electrical systems with different voltage grades, current types and power distribution modes, and defining typical upstream and downstream incoming and outgoing line types.

The basic data interface file should keep the file format of the original electrical design data as much as possible, change the format of the electrical data in a reducing way, and meanwhile, the basic data interface file is most convenient to be butted with an electrical design platform. Therefore, the original electrical distribution feeder table is selected as a basic electrical simulation data interface file.

The power distribution system is connected according to the bus voltage grade, and most high-voltage grade buses provide power for low-voltage grade buses and a small number of buses with the same voltage grade are interconnected. There are ac and dc in bus current type, and there are individual electrical systems that are powered by one selected from a plurality of upstream supplies via static switches. Different electrical systems have different types of power supply upstream incoming branches and downstream to other bus branches of the bus. For the upstream incoming line type, first, primary classification is performed according to the type of electrical equipment flowing through, and the type of the electrical equipment comprises a charger, a transformer (voltage stabilizer), a storage battery pack, an inverter and the like. And then, on the basis of the primary classification, performing secondary classification by judging whether the power supply is switched and controlled by the static switch. In addition, the method can be classified according to the condition that the method belongs to the bus connection at the same level or the condition that the method belongs to power supply outside the design range, and 10 incoming line types are defined in total; similarly, 5 outgoing line types are defined.

And S2, for each typical incoming and outgoing line type, combining the characteristics of the electrical equipment and the requirement of a simulation topology model, and standardizing the topology information requirement of the power distribution network.

The topology information of the power distribution network comprises the connection among buses through incoming and outgoing line branches, the upstream and downstream connection among electrical equipment on each incoming and outgoing branch and the connection of load equipment under the buses. The connection information between the two buses is obtained by selecting a device code of a key device as characteristic data and specifying that the outgoing branch of the upstream bus and the incoming branch of the downstream bus need to simultaneously contain the characteristic data information. If the incoming line upstream direct current passes through the inverter power supply (not through the static switch), the calling relation with the upstream bus is provided through the same inverter code in the bus feeder table of the system. In different electrical systems, the types of the power supply upstream incoming line branch and the types of the power supply downstream incoming line branch and the power supply downstream incoming line branch of the bus to other bus branches are different, and the types of electrical equipment of the corresponding branches and the connection relation among the equipment are also different. Firstly, the interface with the electrical simulation data is specified to contain the type of incoming and outgoing lines, then the specification is carried out one by one according to the type, for example, the incoming line branch switched by the static switch needs to be distinguished from the fixed connection relation of the inverter side branch, the transformer side branch and the static switch, the inverter equipment code of the inverter side, the code of the upstream bus, the transformer equipment code of the transformer side, the equipment code of the circuit breaker on the output side (the incoming line side of the current-stage bus) of the static switch and the like.

And S3, classifying the electrical loads according to the requirements of the electrical load simulation model, and combining the characteristics of the electrical loads to standardize the data extraction requirements of the electrical load simulation model.

The load of the distribution system is divided into various load branches such as medium-voltage and low-voltage infrequently operated loop type, low-voltage reversible motor type, unidirectional rotating motor type and the like. The electrical design verification focuses on whether the power load of a power distribution system meets the design requirement and is matched with the type selection of electrical equipment under different nuclear power plant operating conditions. The simulation depth requirements corresponding to the simulation model are different, the simulation model is further simulated, and the data content requirements of the simulation model are different. Firstly, dividing loads according to the influence degree of the power utilization change of the equipment under different working conditions and selecting characteristic marks. For example, the low-voltage infrequently-operated loop type loads such as a rectifier power supply, a heater, lighting and the like adopt a 'breaker feeder loop' in the design of an electric feeder, the loads do not receive control signals, the power consumption of the loads has no relation with working conditions and can be regarded as the constant power consumption, a corresponding load simulation model can not be associated with a process simulation model, and the power consumption can be simulated according to rated power in a feeder table. Therefore, its electrical artificial load requires the feeder table "breaker model" to provide typical characteristic information (e.g., beginning with the letter "DL"). Secondly, for electrical equipment with power consumption greatly affected by specific operating conditions, incidence relation data between specifications and process simulation models, such as reversible motor type loads of various pumps, fans and the like, needs to be defined, a fuse-contactor feeder circuit is adopted in the design of an electrical feeder, the electrical simulation load needs to ask for the model of the fuse-contactor in a feeder table to provide typical characteristic information (for example, the model is opened by a letter 'CFI'), the power consumption of the electrical equipment is different due to different operating conditions of process system equipment, and the corresponding load simulation model needs to be considered to be associated with the process simulation model. Therefore, the definition specification requires that the feeder table Id-code column must be the bit number of the corresponding process equipment, such as WSC002 PO.

Load design parameter data in electric distribution feeder meters, secondary single line diagrams and working medium flow and power relation data tables of different voltage grades or types in the power plant system are received and converted into electric load simulation calculation information required by a specific electric simulation model.

S4 generating electrical simulation data interface file
