Problems solved by technology

[0003] The current power system outage plan preparation work mainly relies on manual experience, and the traditional method of manually reviewing the operation regulations to arrange the operation mode of the power grid is difficult to meet the operation needs of the UHV large power grid in the future, thereby reducing the adaptability and reliability of the power outage plan.
[0004] Aiming at the poor adaptability and reliability of the above-mentioned outage plan prepared based on human experience, no effective solution has been proposed so far

Embodiment 1

[0028] see figure 1 A flow chart of a method for generating a power outage plan is shown, the method includes the following steps:

[0029] Step S102, obtaining historical power outage data of the current power system; wherein, the historical power outage data includes power outage equipment, power flow data and equipment attributes of power outage equipment; the power flow data includes at least one or more of power load, transmission power and transmission power types; the equipment attributes include unit maintenance period;

[0030] The above historical power outage data can be obtained by summarizing annual and monthly equipment operation data or equipment outage plans reported by lower-level power dispatching agencies.

[0031] Step S104, according to the power flow data and / or equipment attributes of the outage equipment, determine the outage window period of the outage equipment;

[0032] Due to the complex operating conditions of large-scale power grids, power outag...

example 1

[0036] Example 1, associated power outage is the simultaneous power outage of multiple devices that jointly affect the power transmission and receiving capacity of the same area; in order to avoid the simultaneous power outage of related devices with direct electrical connection and weaken the grid structure, search for related devices that are electrically connected to the planned power outage equipment, and conduct Analyze associated outage equipment and form associated outage constraint conditions.

[0037] Example 2. Overlapping power outages are simultaneous power outages of multiple equipment in the same stable section; in view of the impact of equipment outages on the section quota, determine the ownership relationship between the outage equipment and the stable section according to the stability regulations, search for power outage plan arrangements or power outage plan applications, and determine the same In the stable section, whether there are multiple equipment outa...

Embodiment 2

[0067] Corresponding to the above method embodiment, see image 3 A schematic structural diagram of a device for generating a power outage plan is shown, and the device includes the following parts:

[0068] The data acquisition module 302 is used to obtain historical power outage data of the current power system; wherein, the historical power outage data includes power outage equipment, power flow data and equipment attributes of power outage equipment; the power flow data includes at least one of power load, transmission power and transmission power or more; equipment attributes include unit maintenance period;

[0069] A power outage window period determination module 304, configured to determine the outage window period of the outage equipment according to the power flow data and / or equipment attributes of the outage equipment;

[0070] The constraints generation module 306 is used to generate constraints of the power outage plan according to the grid characteristics of t...

Abstract

The invention provides a power outage plan generation method and device. The method comprises steps as follows: historical power outage data of a current power system are acquired; the historical power outage data comprise power outage equipment, power flow data of the power outage equipment and equipment attributes; the power outage window period of the power outage equipment is determined according to the power flow data and / or equipment attributes of the power outage equipment; constraint conditions of a power outage plan are generated according to power grid characteristics of the power system, preset power outage maintenance tasks and operation rules of the power system; the power outage date of the power outage equipment is determined according to the constraint conditions and the power outage window period in the principle that the variance of the number of power outage equipment every day is the minimum. The adaptability of the power outage plan to the current power network is improved, and the reliability of the power outage maintenance plan is further improved.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method and device for generating a power outage plan. Background technique [0002] The power outage plan is to reasonably arrange relevant equipment for power outage maintenance within the maintenance cycle of power transmission equipment, so as to ensure the normal operation of power transmission equipment, ensure the safety of power transmission in the power grid, and meet the transmission capacity requirements of the power grid. The maintenance and outage of equipment will have an important impact on the reliability of the system. Arranging power outages for equipment in a planned way can find internal problems that cannot be found by conventional tests and external observations, and timely discover and deal with hidden dangers of equipment, which is very important for improving the reliability of power system operation. has a very important role. [0003] The curr...
