Example Embodiment

[0061] The present invention proposes a dispatch feedback control system based on regional control deviation and unit generation deviation. It will be described below in conjunction with the drawings.

[0062] Figure 5 Shown is the establishment of a dispatch feedback control system. The dispatch feedback control system includes ACE and a dispatch feedback controller for power generation deviation respectively connected to the unit power generation assessment system, ACE real-time data acquisition system, and ultra-short-term load forecast connection. The unit power generation assessment system and the power plant workstation pass The electric power dedicated data network is connected; the ACE real-time data acquisition system is then connected to the grid energy control system, and the ultra-short-term load forecast is then connected to the grid history database and dispatch production management system. ACE and the dispatch feedback controller of power generation deviation wil...

Abstract

The invention belongs to the field of improvement on power system control technology, and particularly relates to an area control deviation and unit generation deviation-based scheduling feedback control system. By establishing a power grid ACE real-time acquisition system to acquire related frequency, tie-line plan and tie-line real-time data, calculating ACE index values of the power grid per minute and combining ultra-short term load prediction, a novel feedback control system taking load deviation, area control deviation and unit generation deviation into consideration is established so as to guide real-time scheduling of the power grid and establish a corresponding feedback control strategy.

Description

technical field [0001] The invention belongs to the field of transformation of electric power information systems, and in particular relates to a dispatching feedback control system based on regional control deviation and unit power generation deviation. Specifically, through the real-time collection of the regional control deviation of Hubei power grid and the power generation deviation of units in Hubei Province, combined with ultra-short-term load forecasting, a new feedback control system that considers load deviation, regional control deviation and unit power generation deviation is established to guide the real-time scheduling of Hubei power grid. Improve the control performance assessment indicators of the entire Hubei power grid. Background technique [0002] In the power system, the power generation and load power must be kept in balance at all times, so that the power grid can operate stably and the power quality can be guaranteed. [0003] Generating power (MW) =...
