Hydro Network Modeling

Power Costs Inc. has updated its optimization algorithms to include sophisticated hydro network modeling. Optimizing thermal generation, hydro generation and/or pumping resources, reservoirs, and fuel constraints, ancillary services simultaneously is a highly complex process. Adding cascading hydro network, elevation and head-dependent efficiency parameters to the problem is even more challenging. The latest version of PCI GenTrader is deploying the most advanced algorithms to solve these challenges and is taking hydro-thermal and network optimization to the next level. Four key model elements distinguish PCI GenTrader’s enhanced hydro network model:

Complex Topology Users may define a complex hydrological network with reservoirs and ponds and then connect them through waterways. Multiple hydro-electric generators can be fed by reservoirs via penstocks. Pumps can be configured to move water between two reservoirs. Each water path can be constrained with minimum and maximum flow rates expressed in cubic feet per second (cfs). Local inflows (e.g., rainfall) and outflows (leakage and evaporation) can be specified as well. Water level, flow rates, and even spillways can be controlled to achieve desired water management objectives.

Water Measurement

Reservoir elevation is expressed in feet, storage in acre-feet and flows in cubic feet per second. During the optimization process, PCI GenTrader performs the necessary internal conversions as described in the next section.

Non-linear Conversions

A key to incorporating detailed hydro characteristics in any optimization is the inclusion of non-linear conversion curves that define the relationship of water to electrical energy. GenTrader uses such curves for:

Tailrace Representation

In order to accurately capture the efficiency effects of varying head levels, GenTrader explicitly calculates upper reservoir level and tailrace level. Since tailrace elevation can vary significantly with discharge rate, GenTrader includes this calculation to obtain a precise head level.

LVDTs

Alliance Sensors Group is offering a system for drop-in mounting their PGHD series LVDTs for use on GE steam turbines that currently utilize GE’s inductive valve position sensors. These mounting kits utilize the same hole spacing and produce the same center height as the existing GE sensors. They are available for mounting a either a single PGHD LVDT or a dual-redundant stacked pair of PGHD LVDTs. These kits make it unnecessary to design new mounting schemes or to fabricate new hardware when replacing the old GE sensors. The picture below shows how the GEDS kit makes mounting a pair of PGHD LVDTs for dual redundant operation a simple undertaking.

Features of the Alliance sensors PG LVDTs and mounting hardware:

1. Mounting hardware meets the same hole spacing as the GE mounting blocks and produces the same center height

2. Mounting hardware is available in single and dual redundant configurations

3. Dual kit includes tie bar assembly

Linear Position Sensors

LVDT Linear Position Sensors can be repackaged with modern materials to address conditions associated with thorium-based nuclear power and high sulfidation processes associated with heavy oil, process control and bio-chemicals.

Macro Sensors’ HSAR Hermetically Sealed Sensors are constructed entirely of stainless steel along with coil windings sealed against hostile environments to IEC standard IP-68. The conduit exit of these AC-operated sensors ensures a hermetic seal from the operating environment.

For harsher environments, the HLR 750 Series LVDT Linear Position Sensors for Hazardous Locations meet UL and ATEX requirements for Class I Division 1 & 2, Zones 1 & 2. Macro Sensors offers Teflon-free, half bridge versions of these AC-operated linear position sensors that are popular in steam turbine applications in radiation environments.

As passive sensors, the HSTAR, HSAR and HLR sensors can operate in more robust applications, offering a high mean time between failures. LVDT electronics that power these sensors, like Macro Sensors’ EAZY-CAL LVC-4000 LVDT Signal Conditioner, can be partitioned from harsh environments, enabling the Nuclear LVDT sensors to operate under more extreme conditions than is viable with DC-operated sensors having internal electronics.

Proportional Valve Module

WAGO Corp.’s new Proportional Valve Module significantly simplifies the connection of hydraulic or pneumatic valves to the WAGO-I/O-SYSTEM 750. Just 12 mm wide, the compact 750-632 Proportional Valve Module offers a high-performance solution with flexible valve control operation modes.

Two single-coil valves or one dual-coil valve can be controlled either uni- or bi-directionally. For each channel or coil, the output current is 2A in 1-channel operation and 1.6A in 2-channel operation. In connection with a lower set point/actual value deviation, both small and large valves can be controlled reliably and with high repeatability.

The 750-632 features two current-controlled pulse-width modulation outputs (24V) with adjustable dither. Discrete dither frequency setting minimizes the motion, which is adjusted to the valve around the rest position, allowing the set point to be defined without considering static friction. This also prevents the valve from being stuck due to medium residues. Set point definition can be adjusted to the application via both scaling and configurable up/down ramps.

The Proportional Valve Module can operate via any popular fieldbus (e.g., MODBUS TCP, EtherNet I/P, CAN or PROFIBUS) and offers reliable CAGE CLAMP connection technology. Ideal for heavy equipment that uses high-pressure pneumatic or hydraulic valves, the 750-632 can be utilized across a variety of industries, including mining, oil and gas, heavy mobile equipment and metal forming.

Signal Conditioners

Alliance Sensors Group’s S1A and SC-100 DIN-rail-mounted, push-button-calibrated LVDT signal conditioners were developed by listening to customers and LVDT manufacturers’ comments and wish list. This has allowed Alliance Sensors Group to design and build signal conditioners that work with all different types of LVDTs, LVRTs, GE “buck-boost” LVDTs for gas turbines, half-bridge pencil gaging probes, and RVDTs, rather than only satisfying markets where they are strong and not addressing the concerns of LVDT users with other applications.

Solution: S1A and SC-100 LVDT Signal Conditioners offer smart and fast LVDT setup with built-in null indication and simple front panel pushbuttons to set zero and full scale. Calibration time is now reduced from at least 20 minutes per channel to just a minute or two.

The S1A and SC-100 each offer the user:

• Power inputs from 15-30 V DC or ±15 V DC.

• Choice of 4 LVDT excitation frequencies

• Choice of 6 voltage and 2 current loop analog DC outputs

• Unique auto-mastering for master/slave operation – even if a master were to fail, the S1A and SC-100 can eliminate beat frequency effects in remaining units

• RS-485 digital communications link with an available GUI and hot swapability

• Built-in diagnostics for LVDT winding failures or cable disconnection.
