Problems solved by technology

In order to realize this function, the power system also has corresponding information and control systems in various links and different levels to measure, adjust, control, protect, communicate and dispatch the production process of electric energy, so as to ensure that users obtain safe and high-quality electric energy. , but according to the size and demand of different cities, it is necessary to predict the power consumption and load of the city in the process of testing the power system, otherwise when the load of the power system is higher than the maximum load of the urban power grid, it will cause huge accidents. Therefore, it is necessary to invent a kind of urban intelligent control power system to solve the above problems

Embodiment 2

[0024] The power regulation station 3 includes a power forecasting module 31, an early warning regulation module 32 and a load forecasting module 33. The power forecasting module 31 includes power consumption forecasting, power supply forecasting and power generation forecasting. The load forecasting module 33 includes city Combined maximum power load, power supply load, power generation load and generator installed capacity load.

[0025] Forecasting the amount and load of urban electricity consumption is the basis of urban power supply system planning. Electricity forecasting includes: ① Electricity consumption forecasting, including four categories of industrial, agricultural, transportation, municipal and domestic electricity consumption; ② Power supply forecasting, namely Electricity plus grid loss; ③Generation forecast, that is, the power supply plus power consumption of the power plant itself; load forecasting includes: ①The comprehensive maximum load of urban electricit...

Abstract

The present invention discloses an urban intelligent regulation and control electrical power system. The system comprises a power station, the power station is connected with a plurality of area powersubstations through a power transmission network, a connection terminal of an electric regulation station is provided with a power regulation station, the area power substations are connected with aplurality of residential electricity consumption terminals and factory electricity consumption terminals through a supply network, the residential electricity consumption terminals are connected withresidential electricity consumption devices through a power distribution network, and the factory electricity consumption terminals are connected with factory electricity consumption devices through the power distribution network. Through adoption of the electric regulation station, the in-station electric quantity prediction model and the load prediction module in the power regulation station areconfigured to perform data extraction and statistics for electricity consumption prediction, power supply prediction, generation prediction, urban electricity consumption integration maximum load, power supply load, generation load, generator installed capacity prediction in the whole city so as to ensure that the power grid cannot exceed the maximum workload in the working process, and when theworkload approaches an early warning value, an early warning regulation module prompts workers to regulate the power supply of the urban power grid.

Description

technical field [0001] The invention relates to a power system, in particular to an urban intelligent control power system. Background technique [0002] The power system is an electric energy production and consumption system composed of power plants, power transmission and transformation lines, power supply and distribution stations, and power consumption.
