Embodiment Construction

[0021] The present invention will be further described below in conjunction with specific examples.

[0022] A method for composite collection of hydropower dispatching information, which is based on the power dispatching data network, dedicated lines, public communication networks, and safety protection equipment, to construct a composite communication physical link between the main station and the plant station; using classification strategies for subcontracting, data encryption, Secure transmission, package decryption, and independent collaborative correction technologies ensure accurate, effective, timely, reliable, safe and stable application requirements for information collection.

[0023] Construction of composite communication link

[0024] Such as figure 1 As shown, the construction of the composite communication link is the basis of the composite collection method of hydropower dispatching information. It is a multi-channel constructed by making full use of the exi...

Abstract

The invention discloses a hydropower dispatching information composite acquisition method. Based on a power dispatching data network, a special line, a public communication network and a safety protection device, a physical link for information communication between a master station and a plant station is built, policy ranking, packet encryption, safety transmission and autonomous cooperative correction technology are adopted, and a stable, reliable, accurate, high-efficiency, autonomous interactive and self-correction small hydropower dispatching information acquisition composite method is invented, a technical means is provided for full plant station information acquisition of a power grid hydropower dispatching automatic system, small hydropower information acquisition and statistic ability by the automatic system is enhanced comprehensively, acquisition of the small hydropower dispatching information in remote areas without wired network channel conditions can be realized, and the huge information acquisition problem of a small power supply such as a small hydropower station faced by the current dispatching mechanism can be effectively solved.

Description

technical field [0001] The invention relates to a composite collection method of hydropower scheduling information, which is used to solve the problem of information collection of huge small hydropower and other small power sources currently faced by dispatching agencies. Background technique [0002] Statistics from the website of the National Energy Administration show that by the end of 2011, there were 45,000 small hydropower stations below 50,000 kilowatts in the country, with an installed capacity of more than 59 million kilowatts and an annual power generation of more than 200 billion kilowatt-hours, accounting for 30% of the country's installed hydropower capacity and annual power generation. At present, there are mainly three statistical calibers for the sum of power generation and load collected by dispatching automation systems above the provincial level: unified regulation caliber, dispatching caliber and whole society caliber. The statistical data of each caliber...
