Power line carrier communication regulation and control system and method combined with switch conversion device

Abstract

The invention discloses a power line carrier communication regulation and control system and method combined with a switch conversion device. The system comprises a broadband carrier circuit breaker, a broadband carrier concentrator, a communication module and a control end which are connected in sequence. The method comprises the following steps: S1, judging the response qualification of a user; S2, reaching a demand response agreement with the user; S3, monitoring the power load condition by a power master station operation platform; S4, issuing a task by a handheld control terminal according to the power load and the demand response amount; and S5, realizing power load regulation and control through a broadband carrier circuit breaker. According to the technical scheme, a low-voltage user load curve and a power grid load curve are subjected to normalization processing to achieve high matching of the low-voltage user load curve and the power grid load curve, the user air switch qualification is judged according to the coincidence condition of the peak load time periods between the low-voltage user load curve and the power grid load curve, and agreement invitation is carried out on the users meeting the conditions, so that the purpose of intelligent regulation and control is achieved according to the electricity consumption condition.

Description

technical field [0001] The invention relates to the technical field of power load regulation, in particular to a power carrier communication control system and method combined with a switch conversion device. Background technique [0002] According to data, as the peak value of the electricity load of the whole society continues to break through records, the pressure on power grid peak regulation is increasing day by day. The existing power load regulation mainly revolves around the high-voltage demand-side response of large users. The low-voltage demand-side response cannot be implemented on a large scale because it cannot realize precise load remote automatic control, and cannot make timely and effective responses within the response period. [0003] Due to the huge base of low-voltage users, mobilize idle loads of low-voltage users, and through low-voltage demand-side response, let thousands of households participate in the construction of multi-high elastic power grids, ...

Problems solved by technology

[0005] The present invention mainly solves the technical problem that the original technical solution lacks adjustment pertinence and easily leads to adverse consequences, and provides a power carrier communication control system and method combined with a switch conversion device. Integrated processing, to achieve a high degree of matching between the low-voltage user load curve and the grid load curve, and determine the qualification of the user's open circuit through the coincidence of the peak load period between the low-voltage user load curve and the grid load curve between the two. Users make agreement invitations, so as to realize the purpose of intelligent regulation according to the power consumption situation, timely and accurate load control and management, release flexible power load, and enhance the peak capacity of the power grid, which can greatly relieve the load pressure during peak power consumption and achieve peak load reduction. Valley, energy saving and emission reduction, improving equipment utilization, reducing the effect of transmission and distribution infrastructure investment
