Description

INTER-LOCK CONFIRMATION SYSTEM FOR NORMAL CONTROLLING OF ELECTRIC POWER FACILITIES AND METHOD THEREOF}

The present invention relates to an interlock confirmation system for normal control of a field device installed in a substation and a method and a computer-readable recording medium recording a program for executing the same.

In general, after the international standard IEC 61850 for communication of the substation automation system was enacted, high-level operating system products including Intelligent Electronic Device (IED) and Human Machine Interface (HMI) for substation protection, control, and monitoring applied domestically and internationally. The mass production and application of the substation automation system based on IEC 61850 are expanding.

In the IEC 61850-based substation automation system, information is exchanged digitally between a server and a client in an Ethernet environment instead of a one-to-one method using a conventional control cable (Hard-wire).

The substation automation system based on IEC 61850 implements all the facilities that make up the substation with a virtual data model and implements the same data information object in all products.

On the other hand, inter-lock (Inter-Lock) is to control the device does not operate when the electrical or mechanical setting conditions are not satisfied, for example, it is possible to prevent malfunction of the switching device, such as circuit breakers, disconnectors, ground disconnectors, etc. .

The electrical interlock means that the electric circuit is configured to operate the control circuit or the correction circuit of the mechanical correction device only under the condition that the switch can be opened and closed.

The panel with electrical interlock corresponds to one of the control facilities of the 345kV outdoor steel-type substation. In the panel to which the electrical interlock is applied, a single mechanical contact provided by field devices, such as a circuit breaker, a disconnector, and a protective panel, is multi-contacted by using a protective relay. That is, the panel to which the electrical interlock is applied includes a circuit configured by combining multiple contact points. Next, the panel to which the electrical interlock is applied provides output, for example, interlock information to a corresponding field device.

As such, a panel to which a conventional electrical interlock is applied includes a large number of contact protection relays and terminal blocks based on analog technology, thereby frequently causing coil breakage due to contact failure and aging.

In addition, the panel to which the conventional electric interlock is applied has a small space and a complicated back circuit, so it is difficult to find a place of failure when a defect occurs, and it takes a lot of time to repair.

In addition, when a defect occurs in a contact point of a panel to which a conventional electrical interlock is applied, the protective relay may malfunction or malfunction, and a failure in the transmission line may cause the reclose relay to malfunction. In addition, there is a problem in that malfunction occurs due to malfunction due to the release of the interlock, and it becomes impossible to monitor the sky and remotely.

As described above, it is impossible to recognize the situation in the case of a failure of a panel to which a conventional electrical interlock is applied, and it takes a lot of time to identify and repair the failure situation in the event of a failure in the power facility.
