RAPS System Design

Fig. 14.3. Schematic diagram of basic design for RAPS systems.

A common reason for the premature failure of batteries in RAPS systems has been the use of poor quality, or inappropriately designed, batteries. Battery choice is usually determined by economic constraints. Unfortunately, the cheaper the battery, the poorer is the performance. It should also be recognized that some system suppliers lack a fundamental understanding of the lead-acid battery. 

This work investigates the use of reduced order RAP models for the purpose of dynamic simulation, controllability analysis and control system design. Three different discretization methods, namely orthogonal collocation (OC), finite difference (FD) and orthogonal collocation on finite elements (OCFE), are compared. All three methods are able to accurately describe the steady state behaviour. However, the predicted dynamic... 

The Army has a number of options available for the treatment of NSCWM. They include the use of facilities designed to treat both non-stockpile and stockpile CWM, the use of mobile systems that can be incorporated into a facility or transported to the site of a find, and individual treatment technologies. Like mobile systems, individual treatment technologies may be incorporated into a larger entity such as a facility or mobile system or transported to the site of a find. This chapter examines these options, or tools, and, where appropriate, presents the committee s findings and recommendations related to their use. Each facility, mobile system, and individual technology is examined from the standpoint of its current status, as well as technical, RAP, and public involvement issues. An overview of the options for treating NSCWM considered in this chapter appears in Table 2-1.
