원자력 발전소의 제품 데이터 공유를 위한 중립 데이터 웨어하우스 구축

Abstract

During the lifecycle of a nuclear power plant a number of organizations are involved for the plant design, construction, and operation. For example, KOPEC (Korea Plant Engineering Co.) participates in the design stage, Dusan Heavy Industries manufactures the main equipment, a construction company constructs the plant, and KHNP (Korea Hydraulic and Nuclear Power) operates and manages all nuclear power plants in KOREA. Although each organization has an in-house digital data management system and obtains a certain level of automation, data sharing among organizations is poor. For example, KHNP obtains drawings and technical specifications from KOPEC in paper form. This results in manual work of re-definition of the plant model into KHNP system which may cause potential errors in the process. Therefore, a data warehouse based on a neutral model has been constructed in order to establish an information bridge between the design and O&M phases. GPM (generic product model), a data model from Hitachi, Japan is addressed and extended in the present study. Having a similar architecture with ISO 15926 “life cycle data for process plant”, GPM is oriented to nuclear power plants. This paper introduces some implementation results: 1) development of a neutral data model for constructing a data warehouse that can be used throughout the plant lifecycle; 2) 2D P&ID (process & instrumentation diagrams) and 3D CAD model exchanges and their visualization; and 3) an interface between the GPM-based data warehouse and the KHNP ERP system.
