Description: TECHNICAL FIELD The present invention relates to an automatic connection system for an electric circuit network simulator, and more specifically, to circuit elements such as various electric devices forming an electric circuit network in a simulator such as a power system. Automatic connection system that enables arbitrary and automatic connection of the above components.

(Prior art and its problems) Conventionally, as a simulator for analyzing an electric circuit network such as an electric power system, the functions of circuit elements constituting the electric circuit network are equivalently reproduced by components at a certain scale, and There is known a system in which the components of the above are manually connected.

However, this has the disadvantage that the connection work takes a long time and requires a lot of labor, and in some cases, there is a risk of causing an incorrect connection due to a human error, and the efficiency of the operating condition is extremely low. Met. Further, even when the same electric circuit network is configured, the same connection work must be repeated each time, which is extremely complicated.

The present invention has been proposed in order to solve the above problems, and an object of the present invention is to make it possible to automatically connect each component in an arbitrary manner, thereby prolonging the working time and complicated the manual connection work. To provide an automatic connection system for an electric network simulator that eliminates the danger of human error and eliminates the risk of artificial misconnections, and that can easily reproduce the same electric network to greatly improve operational efficiency. is there.

(Means for Solving Problems) In order to achieve the above object, the present invention provides connection information indicating a node indicating a connection branch point of an electric circuit network to be simulated and circuit elements forming the electric circuit network. Based on
An automatic connection control device that determines a connection point of components corresponding to the circuit element and outputs the control signal as a control signal, and an automatic connection matrix composed of a plurality of bus bars in a matrix having bus bars connected to one end of each component. It is characterized in that the intersections of the bus bars are selectively connected by the control signal to connect the components to each other.

(Operation) According to the present invention, a plurality of circuit elements such as electric devices constituting an actual electric circuit network, and a node indicating a connection branch point of the electric circuit network are connected to the automatic connection control device based on the connection information. Is specified. Based on the connection information, the automatic connection control device determines, as connection points, the intersections of the busbars to which the components corresponding to the circuit elements are connected at one end, and sends a control signal to a relay or the like for connecting these intersections. To do.

By this control signal, predetermined components are connected to each other via the intersections (connection points) and busbars, and a simulation model having the same connection mode as the electric circuit network to be simulated is constructed.

(Example) An example of the present invention will be described below with reference to the drawings.

FIG. 1 shows a configuration of an automatic connection system in this embodiment. In the figure, reference numeral 1 is an automatic connection control device (hereinafter, simply referred to as a control device).
On the cable 4, the connection information of the electric circuit network to be simulated (the connection mode of the electric device or the like) is received from the outside, and a predetermined component 3 and a connection point of the automatic connection matrix 2 which will be described later are selected and determined from the connection information. The control signal is output to.

Further, an automatic connection matrix (hereinafter, simply referred to as matrix) 2 is connected to the control device 1 via the cable 4. As shown in FIG. 3, the matrix 2 is configured by arranging a plurality of bus bars X and Y arranged in a matrix according to the total number of components and the number of terminals. As shown in FIG. 4, a relay coil RY that is energized by the control signal is provided at the intersection a where the buses X and Y intersect, and the busses X and Y are connected by closing the contact RY _1. It is supposed to be done.

Referring again to FIG. 1, at the latter stage of the matrix 2, more specifically, at one end of the bus bar Y, the functions of various electric devices and parts such as a generator, a transmission line, and a transformer that constitute an electric circuit network to be simulated are fixed. A plurality of components 3 equivalently realized according to the scale are connected in advance.

Next, this operation will be described.

For example, as shown in FIG. 2, a generator Ge and transmission lines L1 to L
4. Consider the case of simulating a simple electric network consisting of a transformer Tr, a circuit breaker CB, and a load LD, and each terminal of the component 3 corresponding to these is preliminarily attached to one end of the bus bar Y as shown in FIG. Assume that they are connected. Although not shown, generally, a larger number of busbars Y are provided side by side, and one of the remaining busbars Y is connected to another component 3 that is not used this time.

As an automatic connection procedure, first, the connection information concerning the electric circuit network of FIG. 2 is input to the control device 1. This connection information is constituted by a combination of the type of circuit element, in other words, the type of component 3 used for simulation, and the node indicating the connection branch point in FIG. 2, and the connection information in FIG. Step within input step
These are designated by S1 and S2.

Next, it is determined whether or not the input of all the connection information is completed (step S3), and if not completed, the process returns to step S1, and if completed, the process proceeds to the subsequent connection calculation step.

In the connection calculation step, the component 3 specified in step S2 is selected (step S4),
Relay contact according to the node specified in step S1
The intersection a (connection point) of the bus lines X and Y to be connected is determined by RY ₁ (step S5).

After that, by generating a control signal to each relay coil RY corresponding to the connection point determined as described above and outputting this to the matrix 2 as a matrix automatic connection command,
As shown by the thick line in FIG. 6, each component 3 has a bus X,
The Y and relay contacts RY _{1 are} automatically connected to realize the simulation model of the electric circuit network of FIG.

By storing the components and connection points for the same connection information in the memory in the control device 1, it is possible to easily configure a simulation model of the same electric circuit network. It is convenient. It is also possible to connect a part or all of the component 3 to the bus bar X in order to reduce the number of relays at the intersection.

(Effects of the Invention) As described above, according to the present invention, a simulation model of an arbitrary electric network can be configured only by inputting connection information, and the work time associated with manual operation is prolonged as in the conventional case. The complexity can be completely eliminated. At the same time, artificial erroneous connection does not occur, which can contribute to improvement in reliability.

Further, the same electric circuit network can be easily reproduced, and it is possible to provide an electric circuit network simulator which is rich in flexibility and has extremely high operation efficiency.
