Embodiment Construction

[0060] The invention proposes a dispatching feedback control system based on regional control deviation and unit power generation deviation. Be described below in conjunction with accompanying drawing.

[0061] Figure 5 The dispatching feedback control system is set up as shown in the figure. The dispatching feedback control system includes ACE and the dispatching feedback controller of power generation deviation are respectively connected to the unit generation assessment system, ACE real-time data acquisition system, and ultra-short-term load forecasting connection. The unit generation assessment system and the power plant workstation pass through The power dedicated data network is connected; the ACE real-time data acquisition system is connected to the power grid energy control system, and the ultra-short-term load forecasting is connected to the power grid history database and dispatching production management system. For each power plant, the dispatching feedback contr...

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) =...
