Central plant with secondary strong prevention

A method for controlling building equipment comprising a chiller, the method comprising:

• operating the chiller to output supply water at a supply water temperature;
• obtaining a measurement of the supply water temperature;
• calculating an additional load factor based on the measurement of the supply water temperature and a supply water temperature setpoint;
• obtaining an actual load for the chiller;
• calculating an effective load based on the additional load factor and the actual load;
• generating load allocations for the building equipment based on the effective load;
• and
• controlling the building equipment in accordance with the load allocations.

A method for controlling a central plant, comprising:

• operating a first subplant of the central plant to output a first resource with a measureable characteristic;
• obtaining a measurement of the measureable characteristic at an output of the first subplant and a setpoint for the measureable characteristic at the output of the first subplant;
• calculating an additional load factor based on the measurement and the setpoint;
• obtaining an actual load for the first subplant;
• calculating an effective load for the first subplant based on a sum of the actual load and the additional load factor;
• generating load allocations for the central plant based on the effective load;
• and
• controlling the central plant based on the load allocations.
