Description
Technical field
The present invention relates to a kind of instant factory's net exchange method of the real-time generation schedule based on safe II areas, belong to power system
Factory's network data interaction technique field.
Background technology
The intelligent grid supporting system technology network architecture is generally divided into safe I, II, III area, safe I areas deployment
Monitor in real time and the application of early warning class, safe II areas the deployment application of operation plan class and Security Checking class application, safe III areas deployment
Management and running class application.
Current control centre needs to be initially formed planning data file cocurrent after safe II areas carry out generation schedule establishment and is sent to
Safe I areas or safe III areas issue to power plant again.Traditional net interaction of the generation schedule factory based on safe I areas or safe III areas
Mode includes following several：(1) control centre is by each power plant's Plan Curve of safe III areas website orientation, and each power plant is to specified
Voluntarily download website；(2) control centre issues each power plant's plan text by safe III areas power scheduling network or special line passage
Part, power plant's deployment plan downloads work station；(3) control centre issues Plan Curve by safe I areas EMS system telecontrol channel,
Power plant RTU receives Plan Curve.
With intelligent grid supporting system technology real-time generation schedule on-line running and non-AGC units, AGC is not thrown
Function unit participates in the demand of closed-loop control, higher to the interactive real-time of the factory of plan in real time net, stability and interactive proposition
It is required that.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the present invention to provide a kind of real-time generation schedule based on safe II areas
Instant factory's net exchange method, the characteristics of with instant, stable, reliability.
To achieve these goals, the present invention is to realize by the following technical solutions：
The instant factory's net exchange method of real-time generation schedule based on safe II areas of the invention, specifically includes following step
Suddenly：
(1) the control centre's Communications service based on safe II areas, the service of main website of abbreviation II areas are built：
Control centre's Communications service be based on the safe II areas of intelligent grid supporting system technology, be responsible for control centre with it is each
Real-time generation schedule data communication process task between affiliated power plant；
