Description

발전설비 제어용 모의실험시스템Simulation system for power plant control

본 발명은 발전설비를 모의실험(simulation)하기 위한 모의실험시스템에 관한 것으로, 특히 가상의 발전설비를 구축한 가상발전설비구축수단과의 연결을 통해 분산제어수단(DCS;Distributed Control System)의 제어로직을 모의실험하는 발전설비 제어용 모의실험시스템에 관한 것이다.The present invention relates to a simulation system for simulating power generation facilities, and in particular, control of a distributed control system (DCS) through connection with a virtual power generation facility building means for constructing a virtual power generation facility. The present invention relates to a simulation system for power plant control that simulates logic.

기존에는 발전설비(plant)를 제어하는 분산제어수단의 제어로직을 테스트하기 위해서는 소규모의 시험설비(pilot plant)를 건설하여 직접적으로 제어로직 검증을 실시하거나, 소형 입출력장치를 직접 연결하여 일부분만을 선별적으로 테스트하여 분산제어수단의 동작을 검증하였다.Conventionally, in order to test the control logic of the distributed control means that control the plant, a small pilot plant can be constructed to directly verify the control logic, or a small input / output device can be directly connected to select only a part of the logic. The test was performed to verify the operation of the distributed control means.

그러나, 상술한 바와같은 분산제어수단의 제어로직을 검증하는 방법은 아래와 같은 문제점을 가져왔다. 전자의 경우에는 실제 발전설비를 설치하여 분산제어수단의 제어로직을 검증함으로 인한 설치비용이 많이 요구되며, 형태가 다른 발전설비에서는 또 다시 새로운 형태에 맞게 재구성해야하므로 다른 발전설비에서는 그대로 적용할 수가 없다는 단점이 있다. 한편, 후자의 경우에는 일부분의 테스트에 한정되어 있음으로 인해 전체적인 테스트가 불가능하고, 정확한 제어로직 검증이 불가능하다는 단점이 있었다.However, the method of verifying the control logic of the distributed control means as described above has the following problems. In the former case, the installation cost is required by verifying the control logic of the distributed control means by installing the actual power generation equipment, and in other power generation facilities, it is necessary to reconfigure it to the new shape, so that it is not applicable to other power generation facilities. There is a disadvantage. On the other hand, the latter case is limited to a part of the test, the entire test is impossible, there is a disadvantage that the accurate control logic verification is impossible.

따라서, 본 발명의 목적은 위와같은 단점을 해결하기 위해 실제 대상이 되는 발전설비를 가상으로 모델링한 가상발전설비구축수단과의 연결을 통해 분산제어수단의 제어로직을 테스트함으로써 마치 실제 발전설비를 제어하는 것과 동일한 결과를 얻을 수 있는 발전설비 제어용 모의실험시스템을 제공함에 있다.Accordingly, an object of the present invention is to control the actual power generation facilities by testing the control logic of the distributed control means through the connection with the virtual power generation facility construction means that virtually modeled the actual power generation facilities to solve the above disadvantages. It is to provide a simulation system for power plant control that can achieve the same result.
