Problems solved by technology

However, in the current power grid dispatching system, the accident reversal process (PDR) can only reproduce the state changes of the power grid SCADA (Supervisory Control And Data Acquisition, data acquisition and monitoring control system) function, and cannot reproduce the control process of AGC. The correctness and rationality of the AGC control command in the event of a power grid accident cannot be known exactly

Embodiment Construction

[0023] The invention provides a power grid automatic power generation control replay and simulation method, which is applied to the dispatch automation system. On the basis of realizing the automatic power generation control (AGC) power grid power generation model storage and second-level holographic storage of operation process data, it realizes The replay of the whole process of the historical operation of the AGC realizes the simulation of the AGC on the basis of the historical operation section. The replay and simulation of AGC are carried out in an independent replay simulation environment, which does not affect each other with the normal real-time running AGC of other nodes. figure 1 Shown is a system structure diagram of AGC replay simulation in the present invention.

[0024] The technical solution of the present invention will be described in detail below.

Abstract

The invention discloses a repeating and simulating method for automatic generation control of a power grid. The method comprises the following steps of: storing historical editions of a power generation models of the power grid, and storing a new power generation model document of the power grid when the power generation model of the power grid changes; holographically storing AGC (Automatic Gain Control) measuring data, AGC operating parameters and AGC operation supporting data in the AGC operating process by a time sequence database in a second level, and storing associated data in a form of table structure model by a commercial database; and realizing overall repeating and simulation of AGC historical operating conditions. The method can be used for truly repeating the AGC control process in a power grid state evolution process and immediately finding problems of the AGC in the power grid, so that the AGC control policies are improved. Meanwhile, a simulation function based on the AGC historical control section is provided for dispatchers to train simulation of a historical AGC control process section, so that a simulating operation of AGC control is realized.

Description

technical field [0001] The invention belongs to the field of automatic generation control (AGC) in a power grid dispatching automation system, in particular to a technology based on holographic storage technology to provide replay and simulation technology for the historical control process of power grid AGC. Background technique [0002] With the rapid development of the power system, the structure and operation of the power system are becoming more and more complex. In interconnected power systems or regional power systems (national grids, large regional grids, provincial grids or independent power grids) with frequency control or exchange power control tasks In the power grid), it is increasingly important to ensure the frequency quality of the power grid, improve economic benefits and management levels. The automatic generation control (AGC) that undertakes this function is the most important control function in the power grid dispatching system. It requires dispatching o...
