Description

Description: TECHNICAL FIELD The present invention relates to an automatic connection mechanism 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 mechanism 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 requires a long time for connection work and requires a lot of labor, and in some cases, there is a risk of erroneous connection due to human error, resulting in extremely low operational efficiency. Further, even when the same electric circuit network is configured, the same connection work must be repeated each time, which is extremely complicated.

From this point of view, the applicant of the present invention, in the patent application filed at the same time, based on the connection information indicating the node indicating the connection branch point of the electric circuit network to be simulated and the circuit element forming the electric circuit network, An automatic connection control device that determines a connection point of the component corresponding to and outputs it as a control signal, and an automatic connection matrix composed of a plurality of bus bars in a matrix shape in which each component has a bus bar connected to one end, An automatic connection system of an electric network simulator for connecting the components to each other by selectively connecting the intersections of the bus bars by a control signal has been proposed.

With this automatic connection system, each component can be automatically connected in an arbitrary manner, and the same work is achieved by eliminating the work time and complexity of the conventional manual connection work and the risk of artificial misconnection. It is now possible to easily reproduce the electric circuit network.

However, in such an automatic connection system,
One of the matrix buses is selected to connect the components to each other, and the buses between the components may become redundant as the circuit becomes complicated. Therefore, the intervening resistance between the components becomes larger than that in the actual electric circuit network, which makes it difficult to construct an equivalent simulation model.

The present invention has been proposed to solve the above problems, and its object is to reduce an intervening resistance between components connected to each other and to provide an equivalent simulation model of a desired electric network. An object of the present invention is to provide an automatic connection mechanism of an electric network simulator that can be easily realized.

A circuit pattern portion that conducts to a relay contact on a printed circuit board on which the relay is mounted is connected by a branch lead having a low resistance, and the printed circuit board is supported on the bus bar by the branch lead.

(Operation) According to the present invention, a plurality of circuit elements such as an electric device forming an electric circuit network and a node indicating a connection branch point of the electric circuit network are given as connection information, and determined based on this connection information. A control signal is sent to the relay coil at the intersection of the generated bus lines.

Although the relay contacts are closed by this control signal, the circuit pattern parts conducting to these relay contacts are connected to the bus bar made of the low resistance conductor through the branch lead, so that the predetermined components respectively connected to one end of the bus bar are connected. Will be connected to each other with low resistance.

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

FIG. 1 is a perspective view showing an automatic connecting mechanism according to the present invention. In the figure, X and Y represent busbars made of copper or aluminum square bars, and these busbars X and Y are shown.
Are arranged in non-contact with each other in a matrix.
A printed circuit board 1 is arranged above the bus bars X and Y, and a plurality of relays 2 for selectively connecting the bus bars X and Y are mounted on the printed circuit board 1.

The relay 2 has a built-in relay coil and relay contacts (both not shown), the relay coil is connected to an automatic connection control device (not shown), and the relay contacts have a predetermined circuit pattern on the printed circuit board 1. Connected to part 1A. One end of the shortest branch lead 3 made of a low resistance conductor such as copper or aluminum is connected to these circuit pattern portions 1A by means such as soldering or screwing, and the other end of the branch lead 3 is the same. Is connected to each bus bar X, Y respectively.

With such a connection, the printed circuit board 1 is supported on each bus bar X, Y through the branch lead 3.

Here, the connection structure shown in FIG. 1 is for realizing the circuit structure as shown in FIG. 2, for example, and in this FIG. 2, RY is the relay coil of the relay 2 and RY ₁ Represents a relay contact, and a represents an intersection of the bus lines X and Y.

Next, the configuration of the automatic connection system to which this embodiment is applied will be described with reference to FIG. In the figure, 10 is an automatic connection control device (hereinafter, simply referred to as a control device), and this control device 10 receives connection information of an electric circuit network to be simulated (connection mode of electric equipment etc.) from the outside, Based on this connection information, a predetermined component 30 to be described later and a connection point of the automatic connection matrix 20 are selectively determined and a control signal is output on the cable 40.

Further, an automatic connection matrix (hereinafter, simply referred to as a matrix) connected to the control device 10 via the cable 40.
As shown in FIG. 4, 20 is a matrix in which a plurality of bus bars X, Y provided according to the total number of components and the number of terminals are arranged, and as shown in FIG. The Y is connected to the circuit pattern portion 1A on the printed board 1 through the branch lead 3.

Referring again to FIG. 3, at the latter stage of the matrix 20, 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 30 equivalently realized according to the scale are connected in advance.

 Next, this operation will be described.

For example, as shown in FIG. 5, a generator Ge, a transmission line L1 ...
Considering the case of simulating a simple electric network consisting of L4, transformer Tr, circuit breaker CB, and load LD, each terminal of the component 30 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 other components 30 that are not used this time are connected to one ends of the remaining busbars Y, respectively.

As the automatic connection procedure, first, the connection information concerning the electric circuit network of FIG. This connection information is composed of a combination of the type of circuit element, in other words, the type of component 30 used for simulation, and the node indicating the connection branch point in FIG.

Next, the control device 10 selects a predetermined component 30 from the connection information and determines the intersection a (connection point) of the busbars X and Y to be connected by the relay contact.

After that, by generating a control signal to each relay coil corresponding to the connection point determined as described above and outputting this to the matrix 20 as a matrix automatic connection command,
Each component 30 is a bus bar, as shown by the bold line in Fig. 6.
The simulation model of the electric circuit network shown in FIG. 5 is realized by automatically connecting the low resistance path consisting of X, Y, the branch lead 3, the circuit pattern portion 1A and the relay contact.

Incidentally, in the control device 10, by storing the components and connection points for the same connection information in the memory, it is possible to easily configure a simulation model of the same electric circuit network, and it is extremely possible to repeat the simulation. It is convenient. It is also possible to connect some or all of the components 30 to the bus X in order to reduce the number of relays at the intersections.

The above-described embodiment is merely an example, and it goes without saying that the structures and materials of the busbars X and Y and the branch leads 3 are not limited to these.

As described above, according to the present invention, since each component is connected to each other by the low resistance bus bar and the branch lead, it is possible to significantly reduce the intervening resistance between the components. There is an effect that it is possible to easily realize an equivalent simulation model of the electric network.

Further, since the structure is extremely simple, there is an advantage that it can contribute to the cost reduction of the electric network simulator.
