WDS9002 Reservoir Dispatching Automation System for Electric Power Network

Introduction

WDS9002 Electric power network reservoir dispatching automation system, based on the hydrological data telemetering forecasting system, guided by system theory and information theory, builds power network reservoir dispatching database, realizes functions of water status data collection, real time monitoring of multi valleys, water service automatic computation and flood adjustment computation etc. 

Functions

This system adopts multi-layer software structure concept, which is designed according to presentation layer, function layer, and data layer three-layer application model. It keeps ahead to the international level in its integration, openness, real time property, reliability, maintenance, and security. This system can run in C/S mode also can run in B/S mode. 

  • Unified data interface: specification conversion layer is added at the bottom of data transfer layer. The data transfer protocol is unified.
  • Adapt to water status's real time (IN RAM) and historical database: The real time database system is created in the RAM (240 hours' data can be stored), and it can work with the historical database system (RDBMS), which enhances data access speed greatly and also satisfies the requirement of long time historical data storage.  
  • Data refreshing synchronization on WAN: In the large scale reservoir dispatching system formed by multi centers, one data point changes, all the multi centers in the WAN refresh in synchronization. 
  • System design of configuration at method: System can be defined according to the certain application environment. Static information, communication system and MMI etc can be defined and combined freely, which makes the system applicable to any field application. 
  • Water volume balancing computation of multi data type: use the data provided by multi automation system (Set monitoring, EMS, gate automatic control, water status system) including data of electric generator set, gates, ship locks and water level etc and multi static information, computes the water volume balancing automatically to enhance the water volume balancing (computation) automation management level. 
  • Objected oriented MMI design: Object oriented method abstracts the physical object into more than 30 object metafiles, which can be used to form variable MMI for the reservoir dispatching system. 
  • Remote fault removal: creates service software in the running system. When the exception occurs, enter the real time system by PSTN channel or in RAS method, and remove the system fault by the software checking on the client.

Engineering Application

This system has been used in many water dispatching automation systems such as in the Three Gorges of Yangtze River etc.
