Automatic Static Mains Load Optimization; Manual Static Mains Load Optimization - Advanced Energy Thyro-Power Manager Operating Instructions Manual

If the Thyro Power Manager is deployed in replacement, each power controller is switched
into series operations. This is displayed in the following figure:
Figure 17: Current distribution with mit Thyro-Power Manager
The maximum electrical current value is thus now that of a single power controller, and the
start-up time Ts is now 10 * 3 = 30 periods. Thus, the formula may be derived to be:
27 28
If one again assumes the electrical current of a power controller to be I0 = 1, the start-up
time to be Ts = 3 and the elementary period duration to be T0 = 50, the following may be
computed:
In a worst case, the effective value for the electrical current would be 3.18 times higher as
compared to network load optimization using the Thyro-Power Manager.

6.2.1. AUTOMATIC STATIC MAINS LOAD OPTIMIZATION

In operations mode 1, the set elementary period duration T0 (Poti R309) is evenly
distributed onto the number of power controllers (S2).
The start-up time point of each controller is shifted by 5 periods (100ms) in each single
case, as the situation displayed above for e.g. T0 = 50 periods (1s) and 10 power
controllers.
Thus, it results in a more even distribution of electrical power current.
Even groups of power controllers may be connected to an output instead of a single power
controller (see also chapter 4.5.4.2 on page 9). In the course, each controller / group should
provide equal power and carry equal load.

6.2.2. MANUAL STATIC MAINS LOAD OPTIMIZATION

In operations mode 2, the elementary period duration T0 (Poti R309) can be set manually
and in various manners contingent to the number of power controllers (S2). Yet, a
respective PC program or a bus connection is necessary for this. This type of manual
optimization makes sense if each single power controller accommodates strongly differing
target values, or if strongly differing loadings per power controller is deployed, whereby the
working point remains relatively stable, meaning the target values are held relatively
