Abstract: A system for monitoring and controlling a central plant includes a high level optimizer, a subplant monitor, a user interface, and a dispatch graphical user interface (GUI) generator. The central plant includes a plurality of subplants configured to serve a thermal energy load. The high level optimizer is configured to determine recommended subplant loads for each of the plurality of subplants. The subplant monitor is configured to monitor the central plant and identify actual subplant loads for each of the plurality of subplants. The user interface is configured to receive manual subplant loads specified by a user. The dispatch GUI generator is configured to generate a dispatch GUI and present the dispatch GUI via the user interface. The dispatch GUI includes the recommended subplant loads, the actual subplant loads, and the manual subplant loads.

Abstract: A state-based control system for an air handling unit (AHU) includes a finite state machine configured to transition between a high cooling load state and a low cooling load state. In the high cooling load state, the system maintains the temperature of a supply airstream provided by the AHU at a fixed setpoint and controls the temperature of a building zone by modulating the speed of a supply air fan. In the low cooling load state, the system operates the supply air fan at a fixed speed and controls the zone temperature by modulating an amount of cooling applied to the supply airstream by one or more cooling stages. A feed-forward module manages disturbances caused by adding or shedding cooling stages by applying a feed-forward gain to the supply air fan setpoint.

Abstract translation: 用于空气处理单元（AHU）的基于状态的控制系统包括被配置为在高冷却负载状态和低冷却负载状态之间转变的有限状态机。 在高冷却负荷状态下，系统将由AHU提供的供气口的温度维持在固定的设定点，并通过调节供气风扇的速度来控制建筑物区域的温度。 在低冷却负荷状态下，系统以固定速度操作供气风扇，并通过一个或多个冷却阶段调节施加到供给气流的冷却量来控制区域温度。 前馈模块通过对供气风扇设定值应用前馈增益来管理由加法或脱落冷却阶段引起的干扰。
