Embodiment Construction
[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] An embodiment of a method for monitoring voltage loss of important users in a network-saving and land-coordinated power dispatching automation system of the present invention comprises the following steps:
[0023] Step 1: The regional power distribution system establishes the correspondence table between important users and power supply point switches
[0024] The method is as follows: According to the topological relationship of the power grid established by the regional power distribution system, determine the power supply point of each important user, that is, the power point switch of each power supply feeder of the important user, and create important users and their power supply points in the regional power distribution database One-to-many correspondence;
[0025] Step 2, the regional power distribution system receives...

Disclosed is an important user no-voltage monitoring method for a power utilization dispatching automatic system based on provincial and regional cooperation of a network. The method comprises the steps: 1, a regional power distribution and utilization system establishes a corresponding table of important users and power supply point switches; 2, the regional power distribution and utilization system receives switch position-changing information in real time; 3, whether a switch is a power supply point switch of an important user or not is determined according to the corresponding table of important users and power supply point switches; if so, the system records the involved important user names, and a next step is executed; or otherwise, the step 2 is returned; 4, if it is a switch-off signal, a step 5 is executed; or otherwise, a step 10 is executed in a skipping manner; 5, if other power supply points are all interrupted, a step 6 is executed; or otherwise, the step 2 is returned; 6, a no-voltage warning signal is formed; 7, a regional deploying and power utilization system records the warning information and provides data for warning recovery; 8, the warning content is transmitted to a network deploying part through a three-regional network; 9, if it is a switch-on signal, whether it is no-voltage recovery of an important user or not is judged, and a next step is executed; or otherwise, the step 2 is returned; and 10, if it is no-voltage recovery of an important user, warning recovery data is formed.
Description
technical field [0001] The invention relates to a method for monitoring voltage loss of important users in an electricity dispatching automation system coordinated by network, province and land. Background technique [0002] Important users refer to those who occupy an important position in the social, political, and economic life of a country or a region, and the interruption of power supply to them may cause personal casualties, greater environmental pollution, greater political influence, greater economic losses, and serious social and public order. Chaotic power consumers or places with special requirements for power supply reliability. The power supply security of important users has always been highly valued by power supply companies. [0003] At present, network-level dispatchers manage important users through a region-by-level reporting mechanism. This method makes it difficult for network-level dispatchers to understand the power supply conditions of important user...
