  Huaneng Jinling Power Plant Phase II 2*1030MW unit ECMS Introduction

  Huaneng Jinling Power Plant Phase 2 * 1030MW unit ECMS system is my company following the successful implementation of Zhejiang Ninghai Power Plant ECMS, Tianjin North Xinjiang Power Plant ECMS after another one million units of electrical monitoring and management system, the system is designed by the East China Electric Power Design Institute, Electrical communication protocol, at the same time, network computer control system (NCS) is also incorporated into the ECMS.

  Huaneng Jinling Power Plant Phase 2 * 1030MW unit plant 6kV integrated protection and control devices using our WDZ-400EX series of products, 400VPC section with our LPC products, electrical monitoring and management system using our DCAP-4000 products, boost Station monitoring and control devices using our iPACS series of products.

  Electrical monitoring and management system monitoring a wide range, covering: 6kV Auxiliary power system, 400V plant power system, booster station, hair change group, excitation, fast cutting, the same period, diesel generators, fault recorder, UPS, DC system, small current grounding line selection, high standby change, 500kV high voltage protection, generator outlet circuit breaker, generator measurement and control system, main transformer measurement system, generator on-line monitoring, main transformer on-line monitoring, , Low plant temperature monitoring and so on. One of the 6kV Auxiliary electrical circuit, 400VPC into the line, 400VMCC into the line, high and other electrical parts of the use of all communication control, by the independent set of ECMS electrical operator station control instructions.

  In this system, the core components - communication management unit with redundant configuration, communication management unit using our ECM-5900 series of communication devices, the whole plant set up a total of 29 pairs of redundant communication management unit, set up a 25-screen cabinet, which 12 surface plant communication cabinet switch room in situ layout, through the cable access to the relay room station control layer. The system 400V part of the use of PROFIBUS bus communication, the system structure is as follows:
