Embodiment Construction

[0041] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0042] Such as figure 1 As shown, figure 1 It is the flow chart of the land-saving and cooperative operation risk analysis method for ring closure provided by the present invention. The method for ring closure operation risk analysis includes the following steps:

[0043] (1) Set loop closing equipment: dispatch operators to set loop closing equipment according to the needs of the loop closing operation;

[0044] (2) Search the loop closure path: Set the loop closure operation point as the initial node and the termination node, and perform online grid topology analysis according to the breadth priority principle to find the loop closure path; the loop closure path topology information can be displayed on the screen;

[0045] (3) Check the closed loop path: check whether there is a closed loop path, and judge whether the closed loop path i...

Abstract

The invention relates to a method for analyzing safety of a power system, in particular to a method for analyzing risks of provincial and local cooperated closing-loop operation. The method comprises the following steps: (1) arranging a closing-loop equipment; (2) searching a closing-loop path; (3) checking the closing-loop path; (4) generating and splicing a CIM (common information model) model at the local side, and transmitting the model to the provincial side; (5) obtaining and splicing the CIM model at the provincial side; (6) checking and generating an analyzing model at the provincial side; and (7) analyzing the risks of the closing-loop operation at the provincial side. With the adoption of the risk analyzing method provided by the invention, the provincial and local integrated cooperation calculating services can be provided according to the closing-loop needs dispatched at local, the integrated risk analysis results can be given for dispatching operators to reference, and the safety of the closing-loop operation can be guaranteed.

Description

Technical field [0001] The invention relates to a power system safety analysis method, in particular to a land-saving and coordinated loop-closing operation risk analysis method. Background technique [0002] With the development of the national economy, users have continuously improved the reliability of power supply, and the operation and management of the power grid needs to be more reliable, reasonable and efficient. Regional power grids generally adopt ring network design and open-loop operation mode. When the power grid is running, it is possible to perform loop closing and unlooping operations by selecting an appropriate power supply path to enhance the flexibility of power grid operation and reduce network losses. When there is a fault or overhaul in the system, the load at the fault can be transferred through the switching operation, reducing the power supply time and scope, and improving the reliability of the power supply. However, the loop closing operation has the r...
