Project introduction

Project background

1# and 2# generator set of Indonesia Central Java Provin∑ce 2x300MW coal-fired power plant project are EPC projec©t received by China Chengda engineering company. The project contrac♦t value achieves 510 million dollar as the largest project of China in Indonesia, which is brought← into service in October 2006.

Supervisory Information System in Plant Level (SIS) is a factory level monitoring iεnformation system, which is located between the power¥ plant Distributed Control System (DCS) with relevant auxiliary program con★trol system and Manage Information System (MIS) as an important ≠part of digitalized power plant. SIS is able to provide real and reliab±le production real-time and historical data to the decision maker of the power ₹plant as the scientific and accurate product econom↑ic index needed by a marketization power company. SIS mainly targets to the real-time data pr¥ocessing, production process monitoring and management, fault diagnαosis and analysis, performance calculation, analysis and production scheduling. The data €managed by SIS mostly concerns with the production  cost and price information. From the viewpoint of management♠, SIS provide real and important field real-time data to ensure the safety and stable of& power plant, control the cost and increase the company produc→tion, as well as store the amount of historical data of company pγroduction high-effectively and accurately. The historical data logged​ and managed will become the precious resource for comp<any security and Economical Running.

System structure

Generator DCS system with auxiliary system connect♠s to HIRSCHMANN RS2-TX switch by interface computer, where OPC Server is insαtalled as the data acquisition interface on the control layer and SIS layer. The OPC Server of DCS ₹is provided by DCS supplier, while the OPC Server of auxiliary system is suppli€ed by us for free.

Interface computer, database server and applied enginee♠ring station enjoy private 100M passage to connect with RS2-TXγ.

Firewall is designed between the SIS switch layer and MIS layer •to ensure the safety of SIS
